He's the email-checkin'-est guy in the land!
He checks real e-mails from the 'Net
He's got two brothers, and The Cheat, his pet! (The Cheat, his pet!)
There's nobody dumber
Than Homestar Runner
On "The Strong Bad Email Show"!
This was fairly standard for the early sitcom. Later sitcoms moved away from this form in favor of the Thematic Theme Tune, and then toward the Surreal Theme Tune. Today, the Expository Theme Tune is limited mostly to children's programs. Gilligan's Island, the most famous, used it specifically due to Executive Meddling, so that people who tuned in after the pilot wouldn't get lost. Many kids' shows that use it don't even have a pilot, or air episodes out of order. (Animaniacs and Freakazoid! are the big examples.)
Some shows might use the Expository Theme Tune as an excuse to dump you into the action right away, since you already know the premise. Conversely, if the Expository Theme Tune would spoil the premise of the premiere, you might not see it on the first episode.
- BoBoiBoy's theme song lays out its premise: evil aliens come to Earth in search for cocoa and BoBoiBoy is the superhero who must save the Earth.
- The opening of Lamput, as short as it is, still visually conveys the most important information about the show. You see an orange blob who shapeshifts to avoid being captured by two scientists.
- Motu Patlu's theme song, "Motu Aur Patlu Ki Jodi", explains who Motu and Patlu are, how they get along, and what they do.
- Downplayed in Noonbory and the Super 7. The very first lyrics in the theme song ("In Toobalooba there's seven friends/Solving trouble with super senses") mentions the show's premise, while the remaining lyrics are mostly about the Super 7 themselves.
- Both themes of Come to Hoshizora Hall ("Hoshizora Melody" and the Second Night song "Come to Hoshizora Hall") are just songs that explain why the CDs are made, what the cast is planning to do, and what exactly they're giving their Master in thanks for their care and love.
- The children's horror series Vampirates has a theme tune of sorts. It's on the back of the book, and characters sing it in story. It describes the title creatures.
- "Hey, Hey, we're The Monkees / and people say we monkey around / but we're too busy singing / to put anybody down..." (also fits into the category above)
- The Aquabats!:
Sailing on and on and on and on
- Technically this trope but with no actual show to expose at the time, "Theme Song" tells a rather intricate Backstory for the band involving them being driven from their homeland of Aquabania by the evil Space Monster M.
- "The Wild Sea!" is done in the style of one, about a fictional adventure show staring a young man, his father, and their Viking sidekick.
Into the ocean, into the sun
Our boat, a Viking, my dad, and me
On the Wild Sea!
- "Cartoon Heroes" by Aqua is an expository theme of this type for a completely fictional TV show (the video does a good job of being the title sequence).
- Part of the lyrics of "WE ARE MILKCAN!" from Make It Sweet! somewhat describe the basic plot of Um Jammer Lammy:
Suddenly another problem hits us in the face.
And we think that we can overcome this wacky race, but then someone in the band brings up another craze.
- "Whose that jumping out the sky? R-E-Y Mysterio, here we go! When the mask's out the girls they pass out, the boys just blackout, better tap out!"
- "Chris is awesome! He's as hot as it gets, the type to drop you quick, with a mafia kick!"
- "I've got long sideburns. I've got my hair slicked back. I'm comin' to your town in a pink Cadillac. I'm just a Honky Tonk Man (He's just a Honky Tonk Man)! I'm just a Honky Tonk Man (He's just a Honky Tonk Man)! I'm just a Honky Tonk Man! I'm cool, I'm cocky, I'm bad!"
- "Ame...rican! DREAM! (cowbell) He's just a common man, workin' hard with his hands!..."
- Captain Scarlet and the Mysterons. The opening titles have spoken narration. The original closing theme was instrumental, but a group was later recruited to record a vocal version:
Captain Scarlet / He's the one who knows the Mysteron game / and things they plan
- The theme song to Donkey Hodie describes the main character's personality and how she never gives up with any challenge she faces. It also introduces us to her friends.
- The Muppet Show opens every episode by mentioning the special guest, then has the Muppets sing their famous song about how they're going to put on the Show Within a Show.
- The Noddy Shop's theme song has the toys telling the viewers what they should expect to see when watching the show.
Welcome to our place, we've been waiting. Time for some fun and celebrating.
Something is always ready to "pop!", here at The Noddy Shop.
Music and magic. Hey, it's showtime!
Noddy and you will be friends in no time.
Silly 'ol Goblins are living there, too, the place where make believe comes true.
Believe it or not, here at The Noddy Shop!
- The second half of the theme song to The Puzzle Place describes what the show is about, compared to the first, where the kids invite the viewer to visit the titular location.
- The Soldiers Tale begins each act with "The Soldier's March", which commences the rhyming narration before the curtain rises over a steady drumbeat. The reprise at the start of the second act has slightly different lyrics and a brief pause for extra narration.
- Hanazuki: Full of Treasures: "Out there, deep in space, grows a new Moonflower..."
- Homestar Runner:
- In the Strong Bad Email "best thing", there's the theme song from Limozeen: but they're in space!.
Remember those guys from that band Limozeen? / Well, they turned their tour bus into a space machine!

- Baman Piderman: "I'm Baman!" "I'm Piderman!" "I come over da house!" "WE'RE BEST FWIENDS!"
- Actually, the theme song wasn't present in the first two episodes, and the third episode actually involves them creating the theme song.
- Camp Camp has David singing the opening theme, which also doubles as their Camp anthem in-universe.
"Oh! There's a place I know that's tucked away! A place where you and I can stay! Where we can go to laugh and play, and have adventures everyday! I know it sounds hard to believe! But guys and gals it's true- Camp Campbell is the place for me and you!
- Wacky Game Jokez, 4 Kidz! "Mickey was a small time crook on the streets of NYC, he was stolen from the streets by an evil corporation called VGV, he is forced to write direct and star in a video game comedy show broadcasted in the net.."
- Cat Face: Cat Face, he's got a big cat's face, he's got the body of a cat, and the face of a cat, and he flies through the air, 'cause he's got a cat face, Cat Face!
- Bojack Horseman's closing theme: "Back in the 90s, I was in a very famous TV show...".
- Parodied with Martian by Mistake, a nonexistent kids cartoon that is clearly poking fun of this trope and the cliches that come along with it.
- Lee and Dena has a theme song that explains the premise of Lee's series Still Gaming.
"Lee likes playing video games
And when you really think about it, that's not really so strange
But you would wonder if it's why the man was put on this Earth
It's time to reevaluate how much a picture is worth
You can be informed and entertained
No need to explain, watch the review of a game
Lee is Still Gaming!
And I'm pretty sure that is something that won't ever change
Lee is Still Gaming
And it won't just as long as he lives
As long as there are games."
- The Angry Video Game Nerd: "He's gonna take you back to the past/To play the shitty games that suck ass..."

- Atop the Fourth Wall has a theme song that lists off Linkara's name, possessions, and mission, along with some of the stuff he reviews. For his anniversary show, the extended version of the theme appeared, including a verse which focuses on Linkara's pet peeves ("They made Watchmen without the slimy squid") and At4W's supporting characters ("He'll have you know that's pretty low / But not like the standards of the 90's Kid")
- MarzGurl counted down 10 of them from various studios.
- Necro Critic: "We watch crap movies, we play crap games/There's too much out there, causing us pain/The actors are rancid, the plot is stale/Necro is here to put an end to the fail."
- The Legend of Neil's theme song explains exactly how Neil ended up inside the game, then has a very hurried follow-up summarising events up to the beginning of the episode.
- "HE BOUGHT TOO MANY GAMES!/Now we gotta play them all.../SO ALL ABOARD THE STEAM TRAIN!" ("Choo-choo!")
- Several segments of the The Thrilling Adventure Hour feature these. Specifically the intro songs for "Sparks Nevada Marshall on Mars", "The Adventures of Captain Laserbeam", "Amelia Earhart Fearless Flyer", and "Down on Moonshine Holler."
- Who Back When has a theme song describing the fact that they review all of Doctor Who there is. The song lyrics vary based on whether a given episode is reviewing Classic Who, New Who, or Big Finish Doctor Who.
- Shark Jumping, as an homage to the cheesy older TV shows that they riff on.
"There comes a time when life gets you down, when ratings are low. You've got to do what it takes, got to up the stakes, 'til there's nowhere left to go! Shark Jumping! Making some friends on the way together! Shark Jumping! Tomorrow's a brand new day! You might lose some friends along the way, but if you hold your chin up, it'll all be okay! Shark Jumping! That's what friends are, that's what friends are, making our dreams come true!"
