24: Fitting with the premise of the show, episodes are titled with the time period represented during the episode. For example "2:00 a.m.-3:00 a.m.". To disambiguate episodes in different seasons, subsequent seasons named episodes in the following manner: "Day 2: 2:00 a.m.-3:00 a.m.".
100 Questions: Every episode was named after one of the 100 questions in the dating test that served as the driving force for the action. (Therefore, the series was theoretically supposed to end after 100 episodes. It was cancelled after only 6 aired, though.)
1000 Ways to Die: This show consistently uses death-related puns on famous phrases, adages, etc. This applies both to the episode titles and to the individual scenes depicted within. In addition, many of the scenes contain alternate names that play the death pun in a different but still relevant direction.
This Reality TV example titles its episodes "The Girl Who/With ___". (Main drawback: The show has had 4 of its 14 cycles so far end with an episode titled "The Girl Who Becomes America's Next Top Model": cycles 1, 7, 8, and 9.)
Not all episode titles begin with "The Girl;" sometimes they would begin with The Girls. The titles referred to an action that one or several of the contestants took during the course of the episode. Between Cycles 10 and 14 episodes did not begin with "The Girl"/"The Girls" (but they still described events in the episodes).
Anger Management: All the episodes of the TV version have titles beginning with "Charlie", including the pilot ("Charlie Goes Back to Therapy").
Are You Afraid of the Dark?: All of the episode titles begin with "The Tale of", eg "The Tale of the Lonely Ghost" or "The Tale of Laughing in the Dark".
Babylon 5: Though there was no idiosyncratic system for episode titles, every season of this show had one significant episode whose title also doubled as the overall name of the season, fitting in with the concept that the show was a series of novels for television. The titles were "Signs and Portents" (season 1); "The Coming of Shadows" (season 2); "Point of No Return" (season 3); "No Surrender, No Retreat" (season 4); and "The Wheel of Fire" (season 5).
Most of the episodes of the 1960s series have names that rhyme (sometime approximately) two by two. Episodes 21 and 22 of the first season, for instance, are called "The Penguin Goes Straight" and "Not Yet, He Ain't," while episodes 49 and 50 in season two are "Catwoman Goes To College" and "Batman Displays His Knowledge." (Exceptions: "Green Ice"/"Deep Freeze", "The Clock King's Crazy Crimes"/"The Clock King Gets Crowned", "The Greatest Mother Of Them All"/"Ma Parker" and "The Minstrel's Shakedown"/"Barbecued Batman.")
When the format changed in the final season (going from two weekly episodes to one, and fewer cliffhangers), this naming trope was dropped.
BBC: An example of idiosyncratic series naming - this network has broadcast a number of shows that have the aim of finding a new lead for various Andrew Lloyd Webber musicals. Although the format remains consistent from one series to the next, the title changes to reflect the particular musical being auditioned for. In each case, the title is taken from one of the songs in that musical. The four series so far are How Do You Solve A Problem Like Maria? (The Sound of Music), Any Dream Will Do (Joseph and the Amazing Technicolour Dreamcoat), I'd Do Anything (Oliver!) and Over the Rainbow (go on, take a wild guess).
The Beiderbecke Affair: In this Yorkshire Television series, all episode titles are in the form of a question or comment, which is then the first line of dialogue. (E.g., "What I don't understand is this ...")
Bernard's Watch: All episodes of this British children's show had the word "time" in the title (since they were about a watch that could stop time).
Better with You: Curiously, Privileged star JoAnna Garcia's next series also went for this trope - in this case, the episode titles all began with "Better With..." (e.g. "Better With Firehouse").
The Big Bang Theory: Phrases its episode titles like scientific terminology. ("The Fuzzy Boots Corollary", "The Hamburger Postulate", "The Cooper-Hofstadter Polarization", etc.)
Big Time Rush: Almost every episode is named "Big Time _____", except for "Green Time Rush", "Backstage Rush", "Bel Air Rush" and "Welcome Back Big Time".
Every episode title in Blackadder Goes Forth, except the finale ("Goodbyeee"), is a plot-significant pun on a military rank ("Captain Cook", "Corporal Punishment", "General Hospital", etc.) They are also lettered as Plans A-F.
The Blacklist: The post-pilot episodes are named after the episode's target and his/her number on the list (e.g. "The Freelancer (No. 145)," "Gina Zanetakos (No. 152)").
Episode titles are all formatted "The [victim] in the [place]" ("The Woman in the Sand", "The Superhero in the Alley"). Exceptions are "The Man on Death Row" and "The Graft in the Girl", which follow the linguistic pattern but do not refer directly to the victim, and "The Girl With The Curl", which is just out of left field as far as the pattern goes. ("The Truth in the Lye", while a horrible pun, still technically refers to the victim.)
The 4th season premiere had "The Yanks in the UK" which was talking about Booth and Brennan. Possibly, but the victim (and her family) in that episode were also Americans. Booth was asked to help specifically because the victim's father was a powerful American businessman.
The series also varied from the 'victim' format with the over-dramatic title The Pain in the Heart for the third season finale, where Zack is revealed as the Gormogon's apprentice.
Season 5 had "A Night at the Bones Museum", probably because the major murder heavily involved a mummy, and the show already had an episode with "mummy" in its title. There are several other exceptions in this season for varying reasons.
Season 6 contained an episode named The Finder, acknowledging that it was a Poorly Disguised Pilot rather than a real episode.
One first season episode that varied from the "The" format was "A Boy In A Bush". Still held to the pattern, but with A instead of The.
Season 4 also broke the pattern with the episode "The Double Death of the Dearly Departed".
The Season 6 finale "The Change in the Game" plays with the format, as it carries a double meaning; referring both to the case (a dead body found in a pin-setter at a bowling alley) and the Jeffersonian team facing life-changing events (Angela gives birth, Brennan announces that she is pregnant with Booth's baby).
Boston Public: Each episode was named "Chapter _____", with the titular number corresponding to the episode number.
Boy Meets World had many episodes that were puns of movies, music, books, popular phrases, etc.
Bottom: This show used episode titles that could be preceded by the word "Bottom", e.g. "Smells", "'s Up", "Hole", "'s Out" - or more obscurely, "Parade", "Culture", "Burglary" and "Apocalypse".
Breaking Bad: Put together, the titles of the episodes "737", "Down", "Over", "ABQ" give a Spoiler for the season 2 finale. The episodes in question are connected by a strange crime-scene Cold Open with a conspicuous Empathy Doll Shot.
Brotherhood: This Showtime drama had all its Season 1 episode titles as references to religious texts, usually The Bible. The second season uses Bob Dylan lyrics for episode titles. The episode titles for the third season are William Shakespeare quotes.
Bucket And Skinner's Epic Adventures: This show names all of its episodes "Epic _____".
Burkes Law: Every episode of this show, an Aaron Spelling detective show starring Gene Barry, was called "Who Killed _____?" The 1994 Revival, also starring Barry, used the same naming convention.
The Cake Boss: Uses three-word titles with Added Alliterative Appeal that are typically about the cakes they're making plus some hijinks the bakers get up to. For instance "Robots, Rollerskates, and Relatives" had a robot cake, a rollerskate cake, and Buddy's sister and nephew driving him and the staff insane.
Carnivàle: The titles for season two referred to the town in which the Carnivale set up camp - i.e. "Ingram, TX", "Cheyenne, WY", and the finale, "New Caanan, CA" - or where Ben Hawkins was discovering more bits of the endgame - "Alamagordo, NM", "Old Cherry Blossom Road", etc. The first season did this somewhat - "Babylon", "The River" - but if it'd stuck to the trope, we wouldn't have such fun titles as "The Day That Was the Day".
Caroline In The City: The pilot episode used the same title as the series itself, but every subsequent episode title used some variant of "Caroline and the _____".
Castle: In Universe example. Castle apparently loves this since for both the Derrick Storm novels and the Nikki Heat novels the titles all include the main character's last name. Two examples are Storm Warning and Naked Heat.
Charlie's Angels: Both the original and the revived series used the word "angel" in some form in the names of most of its episodes ("Angels in Paradise", "Angel on My Mind", "Angels Go Trucking", "Catch a Falling Angel", "Angels in the Deep" and others).
The name of almost every episode on this show worked on more than one level—each often included a terrible pun which was at least peripherally relevant to the plot point/Monster of the Week, unless the name of one of the sisters was somehow worked into the title. At the same time, most names were also puns which played off of a Shout-Out to another famous title or work. While just about anything was fair game, the most common contenders were works of literature, rival TV shows, classic films, and well-known songs, often oldies. Examples:
Literature: "Something Wicca This Way Comes", "The Demon Who Came in from the Cold", "The Importance of Being Phoebe", "Sense and Sense Ability", "Valhalley of the Dolls", "The Legend of Sleepy Halliwell", "Malice in Wonderland."
TV shows: "That 70s Episode", "Sword and the City", "I Dream of Phoebe", "Spin City", "Styx Feet Under", "Extreme Makeover: World Edition", "Desperate Housewitches", "Rewitched", "The Jung and the Restless", "My Three Witches."
Films: "Dead Man Dating", "From Fear to Eternity", "Secrets and Guys", "How to Make a Quilt Out of Americans", "Apocalypse Not", "Sleuthing with the Enemy", "The Good the Bad and the Cursed", "Death Takes a Halliwell", "Look Who's Barking", "Enter the Demon", "The Three Faces of Phoebe", "Saving Private Leo", "We're Off to See the Wizard", "Y Tu Mummy Tambien", "Baby's First Demon", "Necromancing the Stone", "Little Monsters", "The Courtship of Wyatt's Father", "Crimes and Witch-Demeanors", "A Wrong Day's Journey into Right", "It's a Bad Bad Bad Bad World", "The Bare Witch Project", "Cheaper by the Coven", "There's Something about Leo", "Ordinary Witches", "Charmageddon", "The Seven Year Witch", "Scry Hard", "Freaky Phoebe", "Death Becomes Them", "Kill Billie", "The Lost Picture Show", "Hulkus Pocus", "Mr. and Mrs. Witch", "12 Angry Zen", "The Last Temptation of Christy", "Engaged and Confused", "Gone With the Witches", "Little Box of Horrors."
Songs: "I've Got You Under My Skin", "Dream Sorcerer", "Blinded by the Whitelighter", "Sympathy for the Demon", "The Day the Magic Died", "Nymphs Just Want to Have Fun".
Chuck: This NBC spy comedy titles its episodes "Chuck Vs. ___" (usually a geek reference). The second episode is "Chuck Vs. the Helicopter", which looks funny when you see it on an episode guide after "Pilot". Though "Pilot" has, according to some sources, been renamed "Chuck Vs. the Intersect" to fit the theme.
The Class: This show starts every episode title with "The Class..." followed by a verb phrase describing at least one of the story arcs in the episode and sometimes several.
Comedy Bang! Bang!: Every episode is titled "(Guest) Wears A (Color or Pattern) Shirt & (Color or Pattern) Pants".
Community: This show is set on a community college campus, and every episode features a subtle play on college course titles as it relates to the episode — such as "Football, Feminism and You", "Advanced Criminal Law" and "Social Psychology". Odd Names Out: "Pilot", "Abed's Uncontrollable Christmas", "A Fistful of Paintballs", "For a Few Paintballs More".
Conan: Having episode titles at all is something of a Running Gag for this show, since no late-night Talk Show has ever had them.
Continuum: This show (involving time travel) uses the word "time" for its first season episode titles, like "Time's Up", "Playtime", and "Wasting Time". It uses the word "second" for its second season episode titles, like "Second Opinion", "Second Chances", and "Split Second".
Coupling: One reason why this show has been considered a British version of Friends, is that several episodes have titles staring with "The Girl With" - this was a Running Gag that started when the boys were suggesting names for a hypothetical porn film in which a woman's breasts had independent brains, with suggestions like "The Girl With Two Brains" (Steve: "Three brains, Patrick!") and "The Girl With Two Breasts" (Steve: "That's the worst one yet!"), the latter being the title of the episode. For the record, the name Steve preferred for the movie was "Wobblewars", Patrick's first suggestion.
Covert Affairs: Every episode of the first season (not counting the pilot) is named after a Led Zeppelin song. The second season switches to R.E.M. song titles, the third season to David Bowie song titles (with one song being named after an unreleased cover), and the fourth season to songs by The Pixies.
Damages uses the "bizarre episode name taken randomly from dialogue" trope ("Tastes Like a Ho-Ho", "They Had to Tweeze That Out of My Kidney", "You Got Your Prom Date Pregnant", "Don't Throw That at the Chicken", etc).
Dawson's Creek: During the first season, each episode was named after a classic or popular movie.
The Days and Nights of Molly Dodd: This Blair Brown US TV series had every episode title starting with "Here" or "Here's". Some examples: "Here's why you should always have a cake burning in the refrigerator", "Here's why you should never wear high heels to the bank", "Here's a side effect of serious moonlight", "Here are a few variations on a sexual theme", "Here's the groovy piano bar episode", "Here's a pregnant pause" and "Here comes that cold wind off the river."
Day Break: Each episode has a question as the title: "What If He Runs Away?", "What If It's Her?", since the protagonist is trying new tactics each time the day restarts. (And yes, they all start with "What If...".)
Deadwood: Starting during its second season, this show uses the "random dialogue as episode title" convention.
Deception: This show uses the "random dialogue as episode title" convention (e.g. "Good Luck With Your Death").
The Defenders: The episodes are named after cases ("Las Vegas v. Reid", "Nevada v. Rodgers", etc.)
Degrassi: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras. Though the producers get even more specific. From seasons two through nine it was exclusively 80s songs, before switching to 2000s (with occasional 90s) from season ten onwards.
Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras. Although this is even more specific than other shows.
This show's creator Marc Cherry is a Stephen Sondheim fan, which is why Sondheim songs are used as the titles of episodes (and eventually lyrics from Sondheim songs, since the show lasted for so long). And speaking of series devised by Marc Cherry...
Devious Maids: Each episode after the pilot has a title linked to housework ("Setting The Table," "Cleaning Out The Closet," and so on).
Dirty Dancing TV series: Each episode of this short-lived series shares the title of a different early '60s song.
In Hannah Montana, every single episode title is a riff on a song, including the pilot ("Lilly, Do You Want To Know A Secret?") Other examples include "Oops! I Meddled Again", "Welcome To The Bungle", and "I Want You To Want Me... To Go To Florida".
Several Sonny With A Chance episodes are named "Sonny With A _____", "_____ With A Chance", or vice versa.
Every episode of A.N.T. Farm has the word "ANT" somewhere in it (for example, "TransplANTed" and "America Needs TalANT").
Austin & Ally episodes are an alliterative "_____ & _____" (examples being "Secrets & Songbooks", "Bloggers & Butterflies" and "Girlfriends & Girl Friends"; the only exceptions so far are "Zaliens & Cloud Watchers", "Everglades & Allygators" and the Crossover with Jessie "Austin & Jessie & Ally All Star New Year").
Liv And Maddie has "(word)-A-Rooney", the word related to the A-plot of the episode (for instance, the pilot is called "Twin-A-Rooney").
Has a venerable tradition of titles in the format, "The (noun) of (scary abstract noun)", eg. The Hand of Fear, The Face of Evil, The Reign of Terror, The Seeds of Doom, The Edge of Destruction, The Robots of Death... and so forth. The Big Finish Doctor Who audio drama ...ish hung a lampshade on this when the Doctor mentioned an encounter with the sentient word called The Adjective of Noun. Eventually parodied with Steven Moffat's The Curse of Fatal Death.
After John Nathan-Turner became producer (1980), many stories had one-word titles (e.g. Meglos, Logopolis), often named after characters or planets. Before that, there were three such stories (Inferno, Robot and Underworld) in 17 years.
Stories where multiple doctors meet are called "The <number of doctors that make an appearance> Doctors", except the mini episodes Time Crash and Dimensions In Time and the 50th anniversary special "The Day of the Doctor."
Matt Smith's final three episodes have been The Name of the Doctor, The Day of the Doctor and The Time of the Doctor.
Each finale episode of the RTD era had a title associated with endings (The Parting of the Ways, Doomsday, Last of the Time Lords, Journey's End, The End of Time), but this has changed to beginnings since Moffat took over (The Big Bang, The Wedding of River Song).
Similarly, the first three series of Blake's 7 (produced by David Maloney) had no pattern to the titles. The fourth series (produced by Vere Lorrimer) had all one-word titles.
Don't Trust the B---- in Apartment 23: In the most bizarre naming convention on this page, all the post-pilot episodes of this show have titles which, in order to match with "In Apartment 23", end in an ellipsis...
Dragnet: Almost every episode of the '50s series used a title of the form "The Big _____".
The Drew Carey Show: The first season had many episodes with titles related to chemistry. Also parodied itself with episode 10, titled "Science Names Suck" and episode 15, titled "There is No Scientific Name for a Show About God".
Eastwick: Had many episode titles that combined two rhyming thematic words.
Eli Stone: Every episode of the first season shared its title with a George Michael song.
Ellery Queen: Every post-pilot episode was called "The Adventure of _____".
Emily Owens, MD: Every post-pilot episode has a title that starts with "Emily And...". And unusually, the ellipsis is part of the title (e.g. "Emily And... The Alan Zolman Incident", "Emily And... The Tell-Tale Heart").
Emily's Reasons Why Not: As a special case, had every episode except the pilot have a title starting with "Why Not To", e.g., "Why Not to Date Your Gynecologist". However, only the pilot ever aired in the US.
Everybody Hates Chris: Every episode title has the form "Everybody Hates _____". Including the pilot ("Everybody Hates The Pilot").
Farscape: Featured a lot of idiosyncratic names of episodes. Most were puns which played off of a Shout Out to another famous title or work and managed to tell the audience what the episode was about at the same time. Examples: "A Clockwork Nebari", "Rhapsody in Blue", "Home on the Remains", the entire "Look at the Princess" trilogy specifically "The Maltese Crichton", "I-Yensch, You-Yensch" etc.
Father Ted: Originally, this show was to model its episode titles after the 'Mr Moto' episode titles (e.g. Think Fast Ted, Are you right there Ted?) but the writers could only think of a few examples and dropped the idea.
The Firm: Each episode was named "Chapter _____", with the titular number corresponding to the episode number. Appropriate, given that it's inspired by a novel (or a movie based on a novel).
The Forgotten: Uses "<something> John/Jane" for its titles. This is taken from the practice of identifying unknown victims as John or Jane Doe. Three episode titles however, has Doe instead of John/Jane (namely "Double Doe", "Donovan Doe" and "Living Doe").
Freaks and Geeks: Had many episode titles that combined two rhyming thematic words: "Beers and Weirs", "Carded and Discarded", "Tests and Breasts". Some non-rhyming examples: "Tricks and Treats", "Girlfriends and Boyfriends", "Dead Dogs and Gym Teachers", "Discos and Dragons".
Most likely because the fans will probably refer to the episodes this way anyway, most episodes follow the pattern "The One With _____" or "The One Where _____". The only exceptions are "The One Hundredth", the what-if episode ("The One That Could Have Been") and the finale ("The Last One").
There was actually an interview somewhere in which the writing staff explained that they "wanted to name them what people were going to be calling them anyway".
This was a joke referencing how viewers rarely knew the titles of individual episodes of a television series. Arguably now a case of Aluminum Christmas Trees, as the rise of DVRs (which give the episode title when recording) and internet discussion forums with individual episodes makes The One With trope less true.
The French translators of the show decided for some reason to give up the original kind of Idiosyncratic Episode Naming and replaced it with another one : each episode is named "The One With [insert description of the actions of one character in this episode]". For instance, "The One with Monica and Chandler's Wedding" is translated as "The One Who Married Monica" ("Celui qui a épousé Monica"). It is unknown whether they thought it was a more clever way to do things or missed the point with the first couple of episodes and then thought it was too late to change, but in either cases the titles generally end up being very clumsy, nonsensical and non-informative, making this an example of BlindIdiotTranslation.
Garo has its episodes titled in the same manner as Kuuga's.
Gary Unmarried: Begins every episode title with "Gary" or "Gary's" followed by a description of a person or action.
The George Carlin Show: Every episode was a sentence in the form of George (Predicate): "George Goes Too Far", "George Helps a Friend", etc.
A Gifted Man: This show titles all its post-pilot episodes "In Case Of _____".
Goodnight Sweetheart: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras.
The Good Wife: First-season episodes titles were one word long, second-season episode titles were two words, and so forth through Season Four. Apparently reversed starting with the fifth season, which has three-word titles.
Almost every episode title is a play on a movie title, more than a few of which fall squarely into Incredibly Lame Pun territory. Examples (mostly kept here to titles including main characters or families):
They're also not above riffing on movies with Gossip Girl cast members; witness "The Townie" from The Town (with Blake Lively), "Panic Roommate" from Panic Room and The Roommate (the latter with Leighton Meester in the title role), "Easy J" from Easy A (with Penn Badgley), and the Grand Finale "New York, I Love You XOXO" from New York, I Love You (with Miss Lively again).
Exceptions (besides the pilot): titles which actually are movie titles - "Poison Ivy", "Dare Devil" and "Roman Holiday" (although each one has a double meaning - in the case of the latter it's all in how you pronounce the first name, which rhymes with "Go man").
Grey's Anatomy: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras.
Season one had many episode titles that combined two rhyming thematic words ("In Havoc & In Heat", "Homecoming & Coming Home", "Mistress & Misunderstandings") with the exception of "Hell's Belles" and even that rhymes.
Every episode of season two shares its title with a song, though the songs chosen run the gamut of genres and eras.
Every episode, except for the pilot, uses a Hawaiian word or phrase for its title.
Averted Trope in Season 3 with an episode directed by and starring Peter Weller, named "Hookman" after Weller's character, the main antagonist (although as this was a remake of an episode of the original series, changing the name to fit in with the style was out of the question).
Hellcats: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras.
Honey, I Shrunk the Kids: This TV show titled their episodes as a statement starting with "Honey..." The only exception is "From Honey with Love".
How To Be A Gentleman, How To Be Indie and How To Live With Your Parents (For The Rest Of Your Life): All three shows plumped for episodes with titles beginning "How To..." ("How To Be..." in the case of the first two).
iCarly: The episodes are of the form "i<Insert Phrase Here>", many of which can be read as complete sentences (e.g. "iGive Away a Car", "iSpeed Date") but not all ("iSam's Mom"). This is one of the few series where it also applies to the pilot (called "iPilot").
I Hate My Teenage Daughter: Every post-pilot episode was called "Teenage _____."
In Plain Sight: Episodes are given punny titles often by combining the central element of the episode with a cliche or film or music reference. "A Fine Meth", "Coma Chameleon", "Second Crime Around"...
It's Always Sunny in Philadelphia: Episode titles describe what happens in the episode, usually referring to the main characters as "The Gang." The title card serves as a punchline by bluntly affirming or contradicting the last line of the cold opening. For example, just after Frank insists that no one is going to get hurt by his scheme, the title appears: "Frank Sets Sweet Dee on Fire." It's a little more formulaic than that. The vast majority of the episode titles are <The Gang/Gang member> <verb> <noun/controversial issue>.
Jenny: This JennyMcCarthy sitcom began every episode title with "A Girl's Gotta..."
Joey: This FriendsSpin-Off uses a similar naming convention, in which each episode is titled "Joey and the _____".
John Doe: Most of the episodes have unique names. A few, though, try to reference the title of the show as much as possible, usually involving wordplay. Examples: "Doe Re: Me", "John Deux", "John D.O.A.", "Doe or Die".
Kaamelott: In this French series, seasons are called "Livres" (Books).
Kamen Rider Double uses a "<story arc>/<episode>" format. In addition, each story arc title includes a single Latin letter that stands for two words: a concept central to the arc and a character central to the arc.
Kamen Rider Fourze ups the ante by having four kanji, when put together, make a sentence pertaining to the plot of the episode.
Kamen Rider OOO and its use of the Rule of Three means each title has an "X, Y, and Z" format (eg. A Fist, an Experiment, and a Super Bike; Pride, Surgery, and a Secret; or Chocolate, Faith, and the Power of Justice.)
Kappatoo: As was the case with another British children's show, "time" was put in a plenty of titles (only here it was about time-travelling doubles).
The King of Queens: Episodes of this show that crossover with Everybody Loves Raymond include a pun on Ray in the title. ("Road Rayge", "Rayny Day", "Dire Strayts") All episodes of The King of Queens, except for the pilot episode, have a two word title, usually involving a pun like "Queasy Rider" or an intentional misuse of an existing phrase like "Major Disturbance" ("Major" is the name of Doug's best friend's son).
Knight Rider: Did the same with the word "Knight". Most particularly, the season openers (except for the second season) used titles of the form "Knight of the _____": "Knight of the Phoenix", "Knight of the Drones", "Knight of the Juggernaut". The 2008 revival has returned to this convention, though there isn't too many variations you can take from that pattern.
La Femme Nikita: First-season episodes titles were one word long, second-season episode titles were two words, and so forth (the show ran for five seasons).
The shows in this franchise usually use one-word titles, often using words with a double-meaning. For example, the Law & Order: Special Victims Unit episode "Taken" appears to be about a kidnapping, but it turns out to be a con job. A particularly egregious example would be the episode "Head", about a woman who rapes a boy in a bathroom because she has a brain tumor.
In at least two instances, SVU had two-part crossovers with other Law & Order series using IEN for the titles. A crossover with Law & Order: Trial by Jury was named "Night" (SVU) & "Day" (TBJ). A crossover with Law & Order was named "Design" (SVU) & "Flaw" (L&O prime).
Law & Order: L.A.: Every episode of this short-lived show was named after a neighborhood or area of Los Angeles.
Leverage: Episode titles are all instances of The Crime Job. This is parodied by the creators themselves in the online special The Hand Job: Getting What You Want the Leverage way
Life Unexpected: The episodes are titled as to rhyme with the series title, apart from the pilot, which could also be called Life Unexpected. Examples: "Home Inspected", "Rent Uncollected", and "Bong Intercepted". Unfortunately, they eventually bent this rule. A lot (hence episodes like "Truth Unrevealed", "Music Faced" and "Stand Taken").
Life With Boys: Gives all its episodes titles ending with "...With Boys" (example: "In The Principal's Office With Boys").
The L Word: Every episode title is a word or phrase that starts with the letter "L". Examples are "Longing", "L'Ennui", "Labia Majora", "Life, Loss, Leaving," "L'Chaim," "Lobsters" and "Lead, Follow, Or Get Out Of The Way."
The Man from U.N.C.L.E.: Used titles of the form "The _____ Affair". (Odd Name Out: "Alexander The Greater Affair" - a two-parter, yet.) And each individual act of every episode (until the final season, when they didn't do that for the first act) was subtitled, usually with a quote from the dialogue in that act. Exception: "The Monks Of St. Thomas Affair" used the lines from "Frere Jacques.")
Mash: A considerable number of episodes took their titles from classic movies or songs. These could be either taken straight ("It Happened One Night", "Hey, Look Me Over"), slightly adjusted ("Hawkeye Get Your Gun", "A War for All Seasons"), or turned into horrible puns ("U.N. the Night and the Music", "The Novocaine Mutiny"). The title of the series' final episode ("Goodbye, Farewell, and Amen") was paraphrased from a line in Cole Porter's song "Just One of Those Things".
Maude: Every episode title began with "Maude's ..."
Maybe It's Me, Committed and Opposite Sex: They all called their episodes "The _____ Episode"; Half & Half went a step further, going for "The Big _____ Episode." Fate rewarded this addition by not having this show cancelled after one season, unlike the other three; the TV series of Are We There Yet? has gone for "The _____ Episode", and as the curse has been broken it's also gone beyond one season.
May to December: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras.
Uses the word "Red" in its titles, sometimes fitting the episode (i.e. "Red Hair and Silver Tape" which refers to the trait of the victims and the item used to bind them.)
During the middle of the first season the seemed to run out of "red" puns, so they went with "Scarlett Fever", "Bloodshot", "Carnelian, Inc", Russet Potatoes", all different shades of red, before returning to only red from "A Dozen Red Roses".
Seemingly an Averted Trope in the second season episode "18-5-4", until you realize that R is the 18th letter of the alphabet, E is the fifth, and D is the fourth. The episode deals with cryptography.
Before that, there was another apparent aversion with "Aingavite Baa"- except the title is Shoshone Indian for "red water". The episode is about water pollution on an Indian reservation.
All are a reference to the series' unseen villain and object of Patrick Jane's obsession, Red John.
Following the episode "Red John", where Patrick kills Red John the following episodes drop the red theme but continue to use color-themed naming, i.e., "My Blue Heaven", "Green Thumb", etc.
The Middleman: Every episode is "The _____ _____ _____", such as "The Accidental Occidental Conception". This formula was even used to name the pilot episode "The Pilot Episode Sanction".
Monk: Every episode begins with the words "Mr. Monk", e.g. "Mr. Monk Goes to the Circus", "Mr. Monk Takes His Medicine", etc. (Odd Name Out: "Happy Birthday, Mr. Monk.") Gets a Lampshade Hanging in the episode "Mr. Monk and his Biggest Fan", where Marci tells Monk she has named all of his cases, with the names being the real-world episode titles. Monk is baffled why anyone would bother.
Mr. Show: This show uses the "random dialogue as episode title" convention.
Murdoch Mysteries: The writers are quite fond of using anachronistically modern expressions for episode names, and it very often involves the name of the hero. For instance, the episode about a serial killer who seduced women on line — telegraph lines, that is — is titled "Murdoch.com". Added Alliterative Appeal is used from time to time, as in the episodes "Victim, Victorian", "Me, Myself and Murdoch", "Monsieur Murdoch", and "Evil Eye of Egypt". The template for a title troped as The Joy of X is also employed quite often: "I, Murdoch" (I, Noun), "Me, Myself and Murdoch" (Me, Myself and X), "Dial M for Murdoch" (Dial X for Y), and "Murdoch in Wonderland" (X in Wonderland).
My Place: This is a historical children's series that stretches from 2008 to past 1788. Each episode is in a different decade, and its name is the year it takes placed in.
Nashville: Like several other series here, this show's episodes (apart from the pilot) are named after songs - in the case of season one Hank Williams songs. (That's Hank Williams Sr for the most part, although "You're Gonna Change (Or I'm Gonna Leave)" is from Williams the Younger.)
Season two so far uses songs by female country artists (Patsy Cline's "I Fall To Pieces" and "Never No More," Emmylou Harris's "I Don't Wanna Talk About It Now," and so on).
Neighbours: Had episode titles that form utterly terriblepuns, often based on a song or literary allusion that has something to do with the plot of the episode, such as (this troper's favorite) 'Assault and Pepper'. Thankfully, they have now stopped releasing the names of episodes.
NewsRadio: The last few episodes of this show's second season were named after Led Zeppelin albums, such as Presence and Coda. Just in case you missed the joke, the second and third seasons had episodes titled Led Zeppelin, Led Zeppelin II, Led Zeppelin Boxed Set. Though this wasn't done for idiosyncratic reasons as much as laziness on the part of the writers. (And just in case you were curious, none of the episode titles have anything to do with the episode's contents.)
Nile City 105,6: Taken to the extreme in this Swedish comedy series, where all episodes have the same name: "Adult men do stuff together."
Nip/Tuck: The episodes are named after the main patient undergoing surgery at McNamara/Troy that episode. This has interesting potential for drama; when you see an episode named after a major character, you know something is happening. Of course, it also gave us the episode "Quentin Costa", in which we learn the identity of the Carver, which we had been waiting for for about two seasons. Three guesses what's funny about that title.
Os Normais: This Brazilian sitcom, for its first two seasons, had titles with "Normal" in the title, most usually in the form "_____ is Normal" (exceptions: "Normas do Clube", the club's norms, but one word is just one letter away from "normal"; and "Faça seu Pedido", make your wish). Third season only had it on the season finale, "Finishing is normal".
Paul Almond: In 1964, he shot a documentary for BBC TV detailing the lives and aspirations of a dozen seven-year-olds. It has since been followed by sequels every seven years, all of which were called <multiple of 7> Up, the last being 56 Up.
Perfect Couples: This NBC short-lived sitcom titled all its episodes (save the pilot) "Perfect _____".
Pink Panther And Pals: This show is pretty obvious, as each episode in which the Pink Panther is the protagonist features the word "Pink" somewhere in the title (Subverted Trope with "Pinxillated"). Probably a shout-out to the classic animated Pink Panther shorts (1963-1980) with this naming convention. The 1993 animated series saw several episodes contain the word "Panther" and others that didn't contain either word.
Players: This show, a meeting of minds between Ice-T, Dick Wolf and Shaun Cassidy about con artists, gave all its episodes titles including the word "con" (examples: "Mint Condition" and "In Concert").
Police Squad!: Every episode had two titles. At the end of the intro, the name of the episode would be given on screen, and at the same time, a voiceover would read out a completely different title. Which one was actually relevant to the episode varied. Or just give away who perpetrated the crime in one Who Dunnit episode; screen title: The Butler did it.
Preston Front: This 1990's UK TV series named all its episodes using the format [Character]'s [Object]. This produced titles ranging from the prosaic ("Hodge's Driving Test") to the punning ("Spock's Dilated Pupil" - that's 'pupil' as in 'student') to the vaguely surreal ("Polson's Lilo").
Prisoners Of Gravity: Though never seen by the viewing audience, every episode of this Canadian show about science fiction hosted by RickGreen had a topic-appropriate title with the initials P. O. G.
Privileged: Has all of the episode titles start with "All About...", e.g. "All About the Power Position", "All About Love, Actually" etc.
Public Eye: The British private eye series did the "random dialogue as episode title" thing before The Sopranos (the show's creators were big fans of Naked City, which took a similar approach to its episode titles).
QI: Has series with letters rather than numbers; each episode in the series is given a title that begins with this letter, which serves as the theme for that episode.
The Rat Patrol: This World War II TV show's episodes were always "The _____ Raid".
Rawhide: The first three seasons called every episode "Incident _____ " (e.g. "Incident Below The Brazos"). This was dropped after the first episode of season four ("Incident At Rio Salado"), but returned for seasons five and six; when Bruce Geller and Bernard Kowalski became the new showrunners in season seven the "Incident..." episode naming was dropped for good (as were Geller and Kowalski themselves after a season, but that's another story).
Remington Steele: Incorporated the word "Steele" into its titles, usually as a pun for "steel", "steal" or "still" (e.g. "A Steele At Any Price", "Steele Belted", "Steele Knuckles And Glass Jaws") but not always ("A Good Night's Steele").
Ringer: This show uses the "random dialogue as episode title" convention (such as "The Poor Kids Do It Every Day" and "If You're Just An Evil Bitch, Then Get Over It").
Sam & Cat: The joint spinoff of iCarly (which also used this trope) and Victorious (which didn't) has all its episode titles in the form of Twitter hashtags (e.g. "#FavoriteShow", "#GoomerSitting," and, of course, "#Pilot").
Every episode follows the naming convention "My _____", as it is told from the perspective of J.D., the main character. The only exceptions are episodes told from the perspective of other characters in the show, which are called either "His Story", "Her Story", or "Their Story", with a number.
At one point the writers persuade themselves that they're terribly clever and name an episode "My Ocardial Infarction" (a myocardial infarction is a heart attack).
Season 9, which is from the perspective of the medical students at the new Sacred Heart, uses "Our _____". This was previously used on the Season 8 Webisodes from the perspective of the new interns (mostly Sunny).
Uses a subtler convention, in which each episode follows the pattern "The _____". What followed was a term or important aspect of the episodes story like "The Chinese Restaurant" and "The Serenity Now." The only exception in the entire show's run is the second episode "Male-Unbonding".
Apparently the reason they did it was so they wouldn't spend a whole lot of time thinking of an episode name that people would never see anyway.
Some episode guides list the title as "The Male Unbonding" to bring this one in line with the others.
Sir Terry Pratchett's documentaries for The BBC all have the format Terry Pratchett: Verbing X where X or the verb is to do with life and death: Terry Pratchett: Living with Alzheimer's (about his own condition); Terry Pratchett: Choosing to Die (about assisted dying) and Terry Pratchett: Facing Extinction (about orangutans.)
Skins: The episode titles are the first name of the main character that they focus on. Except the Series 1 and 3 finales, which focus, respectively, the entire cast and most of the cast, and are both titled "Finale". The Series 2 finale also focuses on the whole cast, but is titled "Everyone".
Slings and Arrows: Every episode after the first two was titled with a William Shakespeare quote. More specifically, a quote from the play that was being rehearsed that season (Hamlet in S1, Macbeth in S2, and King Lear in S3).
Smallville: Always uses one-word titles. Except Absolute Justice, which was a double-length episode, so still one word per hour. The two parts are also alternatively titled Society and Legends. The names tend to have obvious ties to the episode and is prone to being dropped. Its pilot episode is simply titled Pilot, in which Kal-El's ship "piloted" to Earth.
Solstrom: This Cirque du SoleilWidget Series, which involved magical solar wind, used the word "wind" or "winds" in every on-screen episode title. For some reason, when it was broadcast in the U.S. the episodes were given plainer titles that dropped this convention ("Howling Wind" became "Gothic", "Once Upon a Wind" became "Adventure", etc.), but the original titles were reinstated for the DVD release.
The Sopranos: After a few episodes, started to have a somewhat idiosyncratic naming convention where each episode had a title that would be spoken aloud by a character somewhere in the episode (one of the best of the early episodes titled in this manner was "Nobody Knows Anything"). AS the series went on, the titles themselves became more idiosyncratic, and some viewers (e.g. Television Without Pity) started actively checking to see how long it took before the writers managed to work the title into the dialogue ("Fleshy Part Of The Thigh", anyone?).
Space Cases: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras. A good deal of the time.
Spaced: Has one-word episode titles, no exceptions.
Special Unit 2: All the episodes for this short-lived UPN show had simple two-word titles that began with "The" - as in "The Brothers", "The Web", "The Walls", etc.
Every episode of season 1 has a one-word title. This troper guesses that if there's a season 2, every episode will have a two word title.
Moreover, every episode of season 1 (so far) has been apparently named based on Elemental Rock-Paper-Scissors: in order, Air, Darkness, Light, Water, Earth, Time, Life and Justice. Where's Fire, you ask? Well, it seems that the Darkness/Light two-parter was originally going to be a single episode, titled, yes, Fire. Half-expecting a Heart episode now.
Sadly, season 2 dropped the theme and just named episodes like they'd normally do. Still, a lot of one word titles...
Still Standing: Each episode begins with the word "Still": "Still Bad", "Still Losin' It", etc.
Strange Report: From ITC and Norman Felton's Arena Productions, this show took its lead from the series title: "Report #(four-digit serial number): (Subject of episode) - (Actual episode name)." (Example: "Report #0649: SKELETON - Let Sleeping Dogs Lie.")
Often names its episodes after classic rock songs — for example, an episode where a town's local children are being possessed is called 'The Kids Are Alright', and the episode where John Winchester dies is called 'In My Time Of Dying'. Many such songs are also played in various episodes, as creator Eric Kripke is a huge fan of classic rock bands likeLed Zeppelin.
Well the first five seasons, at least. After Kripke stepped down as the Showrunner, the episodes are named for other pop cultural references like TV shows, movies, and the like, though a few of them are also named after songs.
J.A.K.Q. Dengekitai: All episodes contained two sentences, the first ending with an exclamation point (or two). For the first twelve episodes, the first sentence consisted of "[Number] [Noun]!!".
Chouriki Sentai Ohranger: A very large amount of episodes had titles prefixed by a one-word sentence ending in two exclamation points. Fifteen of the first seventeen episodes used this scheme, and it became less common after that.
Denji Sentai Megaranger: Every episode title is prefixed by a one-word sentence (sometimes with a particle or two at the end) ending in an exclamation point, except for one where they used a question mark instead.
Engine Sentai Go-onger: Every episode title has its first two characters be kanji, with the remaining in katakana (even words or phrases ordinarily not written in katakana).
Samurai Sentai Shinkenger: Every episode title is written entirely in kanji. Particles (which have no kanji) spoken in the episode title are omitted from the written title, and not a single episode title contains a word of Gratuitous English (as those have no kanji, and aren't necessary for grammar like particles are).
Kaizoku Sentai Gokaiger, like Kamen Rider Decade, names episodes that guest star past heroes in the style of their own series, as per the examples given above. This is only for the episode that features said guest star.
Hikonin Sentai Akibaranger: Every episode title in the first season contains "ita"note "pain", though episode 2 cheats a bit by using it to reference Itasha, which uses the same kanji in them, similar to Abaranger.
Season 2's titles all start with the word "delusion".
Survivor: Starting with Cook Islands, this show refers to its episodes with quotes from the episodes.
The Tony Randall Show: This show, about a judge, phrased every title as a case file, e.g. "Case: His Honor vs. Her Honor."
Torchwood: The episodes of series 3 of this show were simply called 'Day One', 'Day Two', etc. (Unfortunately, the second episode of the first series - in which, as in the second series, there was no particular rule for naming episodes - is also called "Day One".)
True Blood: Every episode shares its title with a song, though the songs chosen run the gamut of genres and eras. Although the songs are often obscure and not well-known. And the song is always played at some point during the episode or over the credits.
Two and a Half Men: This show uses the "random dialogue as episode title" convention (e.g. "Humiliation is a Visual Medium").
Two Guys, a Girl and a Pizza Place: The episode titles were modeled after the title of the show, following the pattern "Two Guys, a Girl and _____". When the show was renamed simply Two Guys and a Girl, the pattern was dropped.
War of the Worlds: Every episode of the first season took its title from a biblical reference.
Watching: All of the titles of this show's episodes are gerunds ("Meeting", "Wrestling", "Outing"...).
The Weber Show (a.k.a. Cursed): Nearly every episode of this short-lived Steven Weber sitcom had an episode title which was some variant of "...And Then (Something Happened)".
What About Brian: The second and last season called each episode therein "What About _____..." (e.g. "What About Calling All Friends...").
Episode titles always began with "The Night of the _____" or "The Night the _____". (Variants: "The Night of a Thousand Eyes", "The Night That Terror Stalked The Town," "The Night Dr. Loveless Died" - except he didn't, "The Night of Jack O'Diamonds"... and the Odd Name Out, "Night of the Casual Killer", although Susan Kesler's book on the series lists it as "The Night of the Casual Killer" to maintain uniformity.)
This style was kept for the French airings (although the series itself is called Les Mystères de l'Ouest), but the episodes themselves don't always have essentially the same titles when translated - for instance "The Night of Jack O'Diamonds" becomes "La Nuit du pur-sang" ("The Night of the Thoroughbred"), "The Night of the Skulls" is "La Nuit des assassins" ("The Night of the Assassins"), and "The Night of the Assassin" becomes "La Nuit de la conspiration" ("The Night of the Conspiracy").
Wonderfalls: Every episode is named after whichever new muse talks to Jaye first in that episode, regardless of that muses significance (in "Crime Dog," the cow creamer is much more present in the story, but the crime dog is the first animal we see talking to Jaye in the episode).
The X-Files: Sometimes used complementary or opposing episode names for multi-part and Myth Arc episodes: "The End"/"The Beginning", "Two Fathers"/"One Son", "Biogenesis"/"The Sixth Extinction I & II" or "Within"/"Without". Most of the time, though, episodes titles for The X-Files were extremely vague words or phrases (frequently in a foreign language) brought up by a single line of dialogue or some other subtle or insignificant aspect of the episode. In addition, the show famously played a game with its fans who tried to find meaning in anything, be it a name of the episode or character or a number combination.
