Raised by Humans: In "Brian Wallows and Peter's Swallows", a bird makes a nest in Peter's beard before being frightened away. The bird had laid eggs in said beard which hatch and Peter ends up taking care of them until they are old enough to take care of themselves and fly away.
In "Play It Again, Brian", Brian delivers one to Peter regarding of how bad a husband he is. However, Peter countered with another one regarding Brian's inability to hold a relationship.
Quagmire delivers one of these to Brian in "Jerome Is The New Black."
Brian is once again on the receiving end of one from Bill Maher, Dana Gould, and Arianna Huffington in "Brian Writes A Bestseller", when he completely dismisses what he said in his own book in a desperate attempt to impress Bill when Brian guest stars on his show.
In "Seahorse Seashell Party", Meg gives one each to Chris, Lois, and Peter.
In "Valentine's Day in Quahog", Stewie calls over all of Brian's ex-girlfriends in order to find out why all of Brian's dates go wrong. While the speech is very brief, all the women tell Brian that he's egotistical, pretentious, insecure, and has a tiny penis. Naturally, Brain denies all the claims and fires back by telling all the women how flawed they are and then tells Stewie that he acts like a woman the most of out everyone in the room. This gets Brian chased by Stewie and all the women down the street.
Repeat Cut: Played straight to the point of being mocked in "Peter's Daughter" with Stewie, Brian, and the exploding, run-down house.
Resentful Guardian: Lois Griffin has been shown to have feelings of contempt towards her daughter Meg for being unable to have an abortion and therefore getting disqualified from participating in the Olympics. Instead she is now stuck raising her.
Road Sign Reversal: Subverted in "Chitty Chitty Death Bang". In order to get the circus parade to come to Stewie's birthday party, Peter looks as though he's going to do this, then he uses the sign to knock out the parade leader and take his place.
Room Full of Crazy: Patrick, Lois's traumatized brother, came to live with the Griffins. His room (actually Meg's) is decorated with photos of himself strangling fat people. And a dead fat guy and a half dead fat guy who then eats the dead fat guy.
Stewie: So we're just gonna look the other way on this one, huh?
Peter gives one to Joe in "Ready, Willing, and Disabled" to build him up during the Special People's Games. Typically of Peter, though, he quickly gets off-track.
Joe: If I couldn't catch a two-bit criminal, how am I supposed to win a race?
Peter: Hey, what kind of talk is that? It's un-American! Did George W. Bush quit even after losing the popular vote? No! Did he quit after losing millions of dollars of his father's friends' money in failed oil companies? No! Did he quit after knocking that girl up? No! Did he quit after he got that DUI? No! Did he quit gettin' arrested for drunk and disorderly conduct at a football game? No! Did he quit...
Joe: I get the message, Peter.
When Peter finds out he is an illegal immigrant in "Padere de Familia."
Peter: This country used to welcome our kind with open arms. But men like Carter Pewterschmidt use us for cheap labor, and then-and then try to punish us when we demand to be treated like human beings. Well, no more! Immigrants built this country, and I say it's time for us to take it back! Who's with me?!
Immigrant: Could you say whole speech again in Spanish?
Rule 34: Reversed with Quagmire in "Family Goy," where he – the sexual deviant who always tries to corral a woman into bed with him, especially if they are older teenage girls – has no concept of Internet pornography, and is teased because of it. By mid-episode, it is played straight, as he gets a huge muscular left arm from masturbating for a few weeks straight.
It's good to know this before criticizing the show for inconsistencies. Seems that many have taken everything ever said in this show as official canon (of some sort) and call "plot hole" whenever a serious-plot moment crops up that contradicts an otherwise one-time gag.
In "Fast Times at Buddy Cianci High", the teachers introduce the various classes at the school. For each class, Peter says, "Ah I love dodgeball/bundt cakes/trombone! Heads up!" The first two times, he throws an object at a random person, knocking them down. The third time, he actually plays the trombone and gets applause... only for Peter to throw the trombone after finishing.
In the Black Eye Griffin segment of "Untitled Griffin Family History", three of Black Eye Griffin's short films end the same way: With the character getting hit in the eye and shrugging at the camera while smiling widely, while "wah wah wah waaaaaaaahh" music plays.
Ollie, with the Blac-u-weather forecast. Originally a one-off (e.g. the Weather Mime), but used more and more since then.
Play me off, Johnny!
In the episode "Saving Private Brian", Stewie terminated this gag with extreme prejudice by shooting Vern and Johnny and proclaiming they will never be seen again. Ironically they were seen again as ghosts in a later episode "Back To The Woods" with Johnny appearing in Hell because, as Vern puts it, "Johnny liked little boys."
Every time "The Bird Is the Word" "Surfin' Bird" is played, after "I Dream of Jesus"
In the earlier seasons, every time Chris did something creepy or questionable Peter or Lois would flatly say "Go to your room."
The idea of Quagmire getting his own spin-off.
Nearly every episode, a character (most likely Peter) would waste an entire minute or two doing something mundane repeatedly (like making 'Dad noises') while any other character nearby would just watch with an unamused looking expression on their face.
Brian inadvertently offending Quagmire via some misunderstanding, leading to a drawn out rage attack from the latter. Possibly Running Gagged since this gag has disappeared for almost a season with only occasional more subdued disagreements between the two afterwards.
A brief one with Stewie in seasons 4 and 5. "WHERE'S MY MONEY, HUH?!?"
Adam West's love affair with everything Eighties and his increasing child-like behavior.
Someone (usually Stewie) will recount something shocking happening, but nobody pays attention.
The evil monkey gag ended in Season 8 when he decided his time in Chris' closet has been enough, and leaves to live in Jake Tucker's closet.
Vern and Johnny get killed about a season after they were introduced. They come back as a Continuity Nod in ghost form.
The Giant Chicken fights. The last time they fought, they made amends and decided to go out to dinner, and they only continued fighting because they were arguing who would pay the check. Every few episodes, a Call Back is made to their dilemma.
Sadist Show: When the show was uncancelled, it contains cheerful bullying of mentally ill, disabled, or terminally ill constitutes an awful amount of the jokes in the series. If someone is in intense pain to the point of suicidal it will almost invariably be mocked and worsened to the extreme.
Samus Is a Girl: In the fourth episode of the series Peter punches out a "guy" who badmouths his son once too often, not knowing "he's" a pregnant woman. Justified as she looks like this◊.
Saving Christmas: In the episode "Road to the North Pole", Stewie and Brian attempt to do this, because Santa is exhausted to near death due to the increasing demand for presents. Predictably, they fail catastrophically.
In the second half of the two-part season 3 premiere, "Brian Does Hollywood", we get to see the nominees for best score at the Adult Movie Awards. Some of the recipients for this particular Woody include John Williams and long-time Family Guy composer Walter Murphy.
One episode centered around Brian's attempts to befriend Quagmire. When he asks why he dislikes him so much, Quagmire goes off on an incredible tangent, obviously voicing the reaction some fans had toward Brian's Author Avatar status, including his religious and political biases.
Combining this with when Quagmire thought he was getting the spinoff and when he was trying to make an improv show, it seems that Seth MacFarlane is using Quagmire as a Self-Deprecation avatar as much as he uses Brian as an Author Avatar.
In the 100th episode special, Seth MacFarlane interviews several people about Family Guy (who don't know who he is). They all say that the show is terrible.
In the 150th episode special, when Brian and Stewie are talking about "Peter's Two Dads" where Peter visited Ireland:
Stewie: Did we explore the effects of the difficult political and agricultural dynamics that have rent Ireland for centuries?
A meta example is that one of the writers is Jewish, and in the commentaries he admits most of the Jewish jokes are his.
Joyce Kinney's real last name is revealed to be Chevapravatdumrong in "And I'm Joyce Kinney". She mentions that her real last name would never be allowed on TV, so she changed it to 'Kinney'. A Co-executive producer/writer of the show is actually named Cherry Chevapravatdumrong.
Self-Serving Memory: When Peter recalls his prostate exam, it is incredibly sinister, and totally wrong.
Sex for Solace: When Peter caught Loretta, Cleveland's wife, having an affair, he found Cleveland's lack of anger to be surprising. Lois suggested getting him to confront his emotions, but Peter instead insisted that Cleveland just needed a "Revenge Lay" in order to deal with the situation. Of course, they never quite got that far...
Shaggy Dog Story: "The Juice Is Loose", where Peter meets OJ Simpson, and, at first, attempts to prove that he murdered his wife and Ron Brown. But then, when he finds out, he despairs that he is innocent and can never get away from the accusations. So Peter lets him stay at his house, but the family is suspicious of him. The entire episode is set up as a twist on the normal narrative about OJ, with him actually being innocent. At the end, the town comes in an angry mob to kick him out, but then O.J. makes an emotional speech about how nobody is perfect, and we shouldn't judge people for making a few mistakes. It works, and the whole town is on his side. But then, he stabs and kills three people for absolutely no reason, and runs off. After which, Peter just nonchalantly says "Oh, I guess he did do it.", and the episode just ends.
In "The Simpsons Guy", Pawtucket Patriots gets sued when it's discovered that the beer is just a rip-off of Duff. Pawtucket ends up losing the case, a big deal because the company is a huge source of income to Quhog's economy, but at the end despite losing Pawtucket stays in business because, as Lois says, "What are they gonna do, come here?"
Shoot the Dog: Literally done by the Board of Directors of the El Dorado Cigarette Company in the episode "Mr. Griffin Goes To Washington".
Shoot the Shaggy Dog: "420" is essentially this: long story short, Brian manages to convince everybody in Quahog to legalize pot, but Carter doesn't like it (it had something to do with his business losing money), and bribes Brian with publishing his horrible novel if he convinces everybody to re-illegalize pot. Brian does, but in the end his novel doesn't sell a single copy. However, this episode was meant to deliver a message about how wonderful everything would be if pot were legal.
Sock It To Them: After Meg gets out of prison, Connie D'Amico and her friends are teasing her in the school cafeteria. Meg ignores them and buys a bunch of soda cans from a vending machine. She loads them into a bag, and uses the bag on the group Batter Up style.
Spoof Aesop: Many of the early episodes ended this way with Peter or another character learning either something completely different from the events they experienced or bluntly admiring to learning jack squat like nothing ever happened. Commentary from Seth and the other writers state that this was their way of ending the episode without filling it with nonsensical bullshit with a mix of the writers not giving a damn how the story ended.
Stable Time Loop: Stewie ends up outside of the space-time continuum and has to overload the return pad to his time machine in order to return to existence. This event turns out to have been the cause of the Big Bang.
Stalking Is Funny If It Is Female After Male: Subverted with Meg usually stalking guys who are nice to her. She stalked Brian, Joe, and Kent. However, it came to a point that her stalking wasn't played for laughs and the police had to stop Meg from raping Brian. Kent once called her a psycho after she attempted to trick Chris into sleeping with him.
Status Quo Is God: A few minor changes have stuck, such as Cleveland moving away (to get his own show) and Brian's relationship status. But for the most part, this is strictly enforced.
Spoofed in "Da Boom", where things are set back to normal by recreating the infamous All Just a Dream ending from Dallas, complete with the original actors.
Another ep has Chris being chased by poachers in Africa. It's never resolved, but during the end credits Stewie says to Brian that "the Chris thing was just a gag, he'll be back next week like always."
Stewie goes to a Star Trek convention because he wants to see the actors from Star Trek: The Next Generation. He finds a Q&A session where all the questions are completely unrelated to show. Stewie is annoyed because the questions aren't about Star Trek. Ultimately he decides to use his time machine to kidnap the cast and force them to hang out with him.
Fan 1: Um, often times my household's sponges accumulate an awful amount of build-up. What can I do to prevent this?
Patrick Stewart: That's an excellent question. It's very important to thoroughly wring out your sponges after every usage. This will prevent the accumulation of grime and bacteria. A dry sponge is a happy sponge.
Stewie: That's not a Star Trek question!
Fan 2: I have a question for Jonathan Frakes. I have this itch on the back of my leg. And I can't figure out if it's a bug bite or dry skin?
Frakes: Do you take hot showers?
Fan 2: Yes.
Frakes: Dry skin.
Fan 2: Thanks.
Stewie: These aren't Star Trek questions, what the hell?
Fan 3: I have a question for Gates McFadden. I've got an artesian well on my property and the water pressure is lousy. Any suggestions?
McFadden: I would check the point first, before re-priming it. But remember that the summer months take a particular toll on any region's aquafer, depending on the local climate.
Stewie: This is horseshit!
Moderator: And that's the last question.
Appeared in a Cutaway Gag to one time when Peter had cow udders. He's making a presentation to a business meeting.
Suckiness Is Painful: In-Universe, Brian's novel, "Faster Than the Speed of Love". In one episode, his book wins an award by a special organization. Emphasis on special, much to Brian's dismay.
Sudden Humility: Peter starts discriminating against Joe for being handicapped, until the feud leads to an accident that leaves him temporarily wheelchair bound. Despite his initial insistence that he will treat his problem with far more dignity than Joe, it takes 40 minutes for him to breakdown from his incapability and apologize to Joe.
Suddenly Ethnicity: Subverted in "Halloween on Spooner Street", in which Quagmire convinces Peter and Joe that he's part Japanese as a set-up for a prank.
Take That: Many cutaways consist of nothing but one of the characters telling an actor how much they suck. Some examples include Peter as Christina Aguilera's manager and Stewie trashing Matthew McConaughey, who doesn't seem to mind.
Family Guy had one at Rugrats in "Love Thy Trophy" when Stewie said he spent all of his money on a "insipid Rugrats video". Hilarious in hindsight when you think Cheryl Chase (voice of Angelica Pickles) is actually a fan of the show according to 100 Greatest Cartoons and was a person that contributed to the DVD sales.
The first thing done once Cleveland returned back to Quaghog was Peter, Quigmire and Joe giving his show a verbal thrashing and how unfunny and unpopular it was despite a very decent four season run.
Peter: You know what else grinds my gears? You, America. FUCK YOU! Diane?
Guy #1: Outrageous! How dare he say such blasphemy?! I've got to do something! Guy #2: There's... there's nothing you can do. Guy #1: Huh... well, I guess I'll just learn to develop a sense of humor...
Another involving Brian and Stewie after they meet Brian's son, apparently directed at those who nitpick every little detail about the show:
Stewie: How can you have a 13-year old son when you're only 7? Brian: That's in dog years. Stewie: I don't understand. Brian: You know what, Stewie? If it bothers you that much then just go on the internet and complain.
The Tape Knew You Would Say That: In one episode, Peter leaves a tape that tries to hold a conversation with Lois to convince her he's actually there. In a subversion, she figures it out when he starts to drift off topic.
Teen Pregnancy: Meg exploits the trope in "Love Thy Trophy" by pretending Stewie is her son.
A more closer example is in "Peter's Daughter", where Meg falls in love with a young doctor named Michael, and has been dating him for a good while, but when the recently overly-protective Peter, who became like this after Meg nearly drowned in the flood, keeps butting in, Michael breaks up with Meg, and two weeks later, Meg believes that she's pregnant with Michael's baby, leading to a Shotgun Wedding. It turns out that Meg isn't pregnant because she had her period.
Teeny Weenie: Peter's been the butt of a few jokes of this nature, as of late in "Christmas Guy" and "Peter Problems".
Temporal Paradox: Brian telling his past self about the terrorist attacks on 9/11 causes George W. Bush in the present time to not only lose the 2004 election, but he also throws a fit and causes the Deep South to break off with the North and basically repeats the Civil War, but with nuclear weapons. This causes Stewie and Brian to go back in time where Brian is about to screw up the timeline and tell them not to do anything in the past. This doesn't go over too well.
Seen in the short "He's Quagmire". A stuffy upper class man said: "I do hope nothing happens to spoil our fancy dinner party." Immediately after, Quagmire jumped on the table wearing a leopard G-string and said "Giggity!" over and over.
Also in "PTV", after the FCC shuts Peter's TV network down, he says that they can't censor the way people live in real life. Three guesses what happens next.
Subverted in "Stu & Stewie's Excellent Adventure" when Peter launches himself with a catapult:
"Excellent! These dominoes are set up exactly as I want them: right next to the good china. Now I'll just place this priceless faberge egg right in the center, next to my newborn, hemophiliac baby."
-Peter lands right outside the window- "Hey, those yours?"
Think Unsexy Thoughts: In "Blind Ambition", Peter, Cleveland, and Joe attempt to teach self-control to Quagmire by sticking a ceiling fan a few inches above his crotch. Quagmire desperately tries to avoid getting an erection by thinking of unsexy things. At first, his examples fail him (dead kittens, nuns, really old nuns), but he's finally able to keep it down by thinking of Renée Zellweger.
Specifically in "The Perfect Castaways" when Brian breaks up with Lois:
Stewie: "Ah, bitch, you got jacked, bitch."
This Loser Is You: Being a satire, that's the entire point of the show. Peter in particular is supposed to carry this message, however whenever any character is being a hypocritical (uneducated) bigoted jerkass, you can bet the writers are winking right at you, or at least at the society we live in. It only gets more hilarious - or depressing - when a lot of people who watch and enjoy the show think all the gags and jokes are not meant to be funny because of the critique and irony that lays behind them, but just because they're actually funny per se.
Throw the Dog a Bone: While she still is picked on, the writers have started to tone down the Meg bashing in later seasons.
Spoofed in "420" where Peter is shown being amused by various title drops in films ("The only way I can stop this crisis is by being Superman IV: The Quest for Peace!") Then later, a walk-on character says "I'm a family guy!" and Peter is thrilled.
Brian said "Stewie loves Lois!", which is the title of that episode.
Title Please: Exceptions being the Brian & Stewie "Road To..." episodes and "Viewer Mail #1", which had three different title cards for each segment.
Toad Licking: "Toad" becomes such a popular fad at James Woods High School, after a Colombian drug cartel's plane transporting the toads crashes near Quahog, that Peter winds up going undercover at the school as "Lando Griffin" to get the students to stop.
There was even a hilarious anti-drug PSA directly spoofing the classic Tootsie Pop commercial with Mr. Owl.
Kid: Mr. Toad, how many licks of you does it take to get to the center of a Rhode Island State Prison?
A lot of Family Guy episodes (particularly those aired after the show was Un-Canceled in 2005) have a lot of scenes and lines that FOX censors won't air or were cut due to time constraints. Cartoon Network airings partially restore some of the scenes and lines that were edited on FOX, but the DVD has all of the scenes and lines that were rejected by censors (either in the episode proper or as part of a deleted scenes reel)
Also, two episodes were banned: "When You Wish Upon A Weinstein" (was banned out of fear that Jews and Catholics would find the show's take on religion offensive. The episode aired years later with a line change and some light trimming of one scene) and "Partial Terms of Endearment" (banned for dealing with the hot-button topic of abortion. The episode did air on a UK TV channel and was released on DVD, but FOX is never going to reverse its decision not to air the episode and Cartoon Network might not air it, either).
One episode had Joe regain the ability to walk, which boosts his confidence level tenfold. However, he gets a little too overconfident and starts to berate his friends for not meeting his high demands to improve in whatever activity they are doing. He even ditches Bonnie (who is still pregnant) and his friends to be with friends that he says are not lazy and can keep up with him. It takes Joe losing his ability to walk again to bring him back down to humble levels.
Meg had become less of a brat and became more humble due to the entire world treating her like crap. However, in "Chris Cross", Meg witnesses Chris stealing money from Lois' purse and decides to blackmail him by forcing him to do all her chores and other tasks while she acted like a smug jerk throughout it all. After Chris had enough and decides to run away, Meg tells Chris that he's a fat loser with no friends and he has nowhere to run away to. Compared to the childish insults that the rest of the family dishes to her, Meg's comments to Chris is quite harsh.
Speaking of Chris, he's been like this since Season 11. See "Secondhand Spoke" and "Herpe, the Love Sore" as a shining example.
Ross Fischman was friendly and down-to-Earth in his first appearance. When he returns in "Into Fat Air", he's a smug jerk who brags about how much better his family is than the Griffins.
Similarly Meg, originally a Bratty Teenage Daughter that was ashamed of her family's antics, has become more docile and friendly, if only in her desperation for her family's love.
Touch of Death: When Death Takes a Holiday and Peter needs to fill in for him, simply wearing Death's shroud causes anything Peter touches to instantly die, even without intending it. He learns this the hard way.
Train Job: Subverted. Peter and his father-in-law, Carter, try to do this, but the ticket taker tells them that no one rides the trains anymore.
Tranquillizer Dart: In an early episode, Peter's boss devises a contest for the company picnic, which involves taking shots at the employees with a tranq rifle and seeing who can last the longest. Most of the employees drop like stones the moment they get shot... except for Peter, who ends up with more than a dozen tranquillizer needles stuck in him, and still manages to stay conscious long enough to win the contest. It would seem that this is either due to his relatively high body mass, which (in theory) would require longer for the chemicals to spread through his body, or due to the increased amount of fatty deposits, which would help isolate the venom from his bloodstream.
Transsexual: Handled with all the tact that a character vomiting for 28 seconds straight can bring to a topic. Although the show does deserve credit for Quagmire adamantly claiming that being a transwoman who is interested in men does NOT constitute being a gay man; it constitutes being a straight woman born into a man's body.
Woman: You know, I had such a great time with you last night. Toilet: Listen, there's something I have to tell you. I just got back from the doctor. I have herpes. I think you should get yourself checked out. Woman: Oh my God! Toilet: Will you stay? Woman: What? Toilet: Will you stay with me, even knowing that I have herpes. Woman: (Beat) Yes, I will. Toilet: ...Joanie? Woman: Yeah? Toilet: I don't have herpes. I just needed to know that you'd stay.
True Love Is Boring: Zig-zagged. Lois and Peter have had numerous ups and downs (including infidelity at one point), but they are still together.
Un-Confession: Played for Laughs; in keeping with the show's increasing reliance on shock value, it normally involves Peter being a total Jerkass when inappropriate, or Lois admitting to some past (wild) indiscretion. She learned that from her father, who also does it often.
Unexplained Recovery: Happens quite often, given the random Cutaway Gag nature of the show, but Meg is killed for the sake of a joke more often than most, but is fine in the next scene. For example, in "Space Cadet", the whole family gets trapped in space on the space shuttle. Stewie looks on the monitor to see Meg poking around the cargo hold, and tells Brian he's going to give her a scare. Stewie hits a button, opens the cargo hold, and Meg gets blown out into the eternal depths of space. Without making another sound, a look of horror slowly creeps across both their faces as they realize just what happened, and Brian closes the cargo hold and turns off the monitor. In the next scene, she's back to normal without mention. Among other methods that she's been killed were being shot with poison darts while running from a tribe of natives, having her heart ripped out for interrupting a Jewish prayer at dinner, and being shot in the face by Peter just for casually walking past him and saying hello.
The Unfair Sex: Lois, despite often proving to be a terrible human being and a hypocrite on top of it, is generally given moral superiority over Peter in just about everything.
Brian is also depicted as a vile, terrible lover in later episodes. While this is hardly a false statement, it rarely acknowledges that half of his girlfriends are also hypocritical Jerkasses who barely deserve any better.
Unusually Uninteresting Sight: Seriously, when is someone going to find it weird that a dog can do things that normal people can do like talk, drink, smoke, and have sex with human females... that and the baby can talk.
Uptown Girl: Lois and Peter, as shown by an early episode where Peter is at odds with her tyrannical father in order to gain his approval, which he never does. She marries him despite her father's insistence that she doesn't really love him or his covert attempts to kill Peter.
Vehicle Vanish: Subverted. "It would probably have been a good idea to get on that truck."
Villain Song: In "Lois Kills Stewie", after successfully taking over the world, Stewie sends a broadcast out to the entire population on various (and gruesome) forms of punishment he will administer to those who irk him. The song is essentially the entirety of his Enemies List, and is put to the tune of The Mikado'sThe List Song.
Vinyl Shatters: In the episode "I Dream of Jesus", Brian and Stewie break Peter's Surfin' Bird record; Stewie stomps on it with his foot and Brian smashes it further with a baseball bat.
Vocal Evolution: Stewie had a lisp with his accent, and Brian, Quagmire, and Meg all had much higher voices in the pilot episode, "Death Has A Shadow". Also, Chris's voice constantly shifted as though he was going through puberty.
Vomit Indiscretion Shot: Used every time somebody throws up, which is not rare. Taken Up to Eleven in the episode "Quagmire's Dad" where Brian vomits for almost 30 seconds straight without stopping.
Used to the extreme in "8 Simple Rules For Buying My Teenage Daughter" where Peter, Chris, Brian, and Stewie drink medicine that induces vomiting and have a contest to see who can be the last guy standing before vomiting. Nearly a minute or two of this gag involves nothing but the four guys vomiting constantly all over the living room.
"Who wants clam chowder?"
War Memorial: Mayor West commissions a war memorial to honor Quahog soldiers who perished in the Gulf Conflict. Unfortunately he chooses a solid gold statue of Dig 'em the Sugar Smacks mascot, which is completely inappropriate and drains the town's coffers, leading to protests calling for his resignation.
"I Am Peter, Hear Me Roar": Peter is sent to a sensitivity camp to deal with his outrageous sexism. When he returns with a more sensitive and mature (albeit comically feminine) understanding of how to treat people, it makes his friends and family very uncomfortable and they try to figure out how to turn him back into a misogynist again.
"I Never Met the Dead Man": Peter is forced to cope without Cable TV throughout Quahog, and as a result becomes a happier, active person who genuinely enjoys family life and just living in general. Even though this was Lois' idea, she tries ineffectually to get him out of it. The solution appears nigh when William Shatner's car breaks down in front of the Griffin's house on his way to a conference on how television is great for people's lives...but then Peter gets Shatner to come with him to the Bavarian Folk Festival instead, where Shatner renounces the emphasis TV has had on their lives. Don't worry, Peter's still turned back to a TV-watching slob by the end of the episode.
Welcoming Song: "This House Is Freakin' Sweet", when the Griffins inherit a mansion, all the mansion's staff sings a song welcoming to their new lifestyle. The song's a parody/Suspiciously Similar Song to the welcoming song "I Think I'm Going to Like it Here" from Annie.
The premiere of season 9 kills off no less than three recurring characters, one of whom had been around since the beginning of the series.
The hurricane crossover. Meg gives most of the family a "The Reason You Suck" Speech, particularly towards Lois. This was similar in tone to "Brian and Stewie".
"Life of Brian": Brian is Killed Off for Real. No really, he's dead. Stewie trashed the time machine and he can't get the parts to fix it again. Meaning he can't go back and save him. The Griffins get a new dog, Vinnie, who, after a bumpy start, manages to console and befriend Stewie.
Wham Line: From "Brian and Stewie", when Stewie asks Brian has a gun in his safety deposit box.
Brian:I keep it in case...I ever want to commit suicide, okay?
Neil Goldman. Okay, he was sort of Demoted to Extra at first, but the entire Griffin family got invited to James Woods's mansion...and yet only the Goldman parents were invited? A few episodes later, in "Road to the North Pole", we see Mort Goldman making some remarks related to him being Jewish in the context of a song about what the characters want for Christmas...with Neil nowhere in sight. Where the hell is he?
Quagmire's Littlest Cancer Patient niece (whom Brian mistook for a boy, and further cemented Quagmire's resentment for Brian) in "Road to the North Pole". She was hospitalized somewhere around the start of the third act and that was the last we heard of her.
The Campbells, the nudist family. They appeared in two episodes early in 2002, and then they completely disappeared except for a short cameo eight years later.
Although he was never given a name, there's the conspicuous absence of Carol's son, whom she conceived with her eighth husband. Lois and Peter were the only people present at his birth back in the early seasons (discounting an unconscious Dr. Hartman) and this event in turn inspired them to want to have more children of their own for a short while. Fast-forward a few seasons, and Carol's married and divorced her ninth husband, leading her to move in with the Griffins — and yet her son, who couldn't be that much older than a baby, is nowhere to be seen. Then she marries and moves in with Mayor West in a record amount of time and STILL her child isn't even referenced, let alone taken along. Was he adopted? Did he die? Does anyone even CARE that Lois and Peter's nephew has melted into thin air?
Remember when Meg had friends? No? Neither does Seth, since they seemingly phased out into nothingness halfway through Season Four.
White Anglo-Saxon Protestant: In "The Son Also Draws", Peter shows Chris a family of WASPS; not the animal, but a family of White Anglo Saxon Protestants who make passive-aggressive remarks towards each other at dinner.
Wire Dilemma: In the opening to "Brian Does Hollywood", Meg's trying to disarm a bomb.
Meg: What do you mean, "cut the blue wires"? They're all blue wires!
Wise Beyond Their Years: Stewie is one year old but can build multi-verse transporters, time machines, and laser weaponry.
Women Are Wiser: Initially at least, Lois was far more rational and intelligent than her husband. As the shows Comedic Sociopathy kicked in however, Lois became more hypocritical, self righteous and out and out sociopathic, though still tends to be given higher moral ground than Peter (who is usually even worse).
Inverted in 'Forget-Me-Not' Where Peter, Brian, Joe and Quagmire all try investigating what happened after they wake up in a deserted Quahog with no memory and only resort to violence when they find evidence saying Peter killed everyone else. While Meg, Bonnie and Lois are put into the same scenario but immediately start fighting each other without saying a word.
Working on the Chain Gang: In the episode "Holy Crap," Peter has kidnapped the Pope by posing as his driver and he drives the Pope Mobile past one of these. The Pope doesn't realize anything is wrong and keeps waving at everything, including a chain gang, parodying Cool Hand Luke:
Luke: (takes his shirt off) Taking it off there, boss.
Guard: Take it off there, Luke.
Luke: (wipes sweat off his face) Wiping it off there, boss
Guard: Wipe it off there, Luke.
Luke: (waves at the Pope) Waving at the Pope there, boss.
Would Hurt a Child and Would Hit a Girl: Bread-and-butter tropes in the series. Most often employed by Peter, who has no qualms hitting Lois and/or Meg on many occasions, and he has put Meg in extreme danger on several other occasions, such as in "Peter's Daughter," where he forced her to go into the flooded basement to get a can of beer from the submerged refrigerator.
Peter's assaulting children should get him arrested, convicted and a lengthy prison term. However, he is allowed on at least one occasion to beat Lucy Van Pelt (from Peanuts) to an inch of her life when he kicks her head and slaps her repeatedly ... all for the "felony" of moving a football out of the way before Charlie Brown can kick it. Peter finally knocks her unconscious when he gives her a roundhouse kick to the back of the head for the capital crime of ... not being a licensed therapist! (Both the football and therapist gags were recurring stories in Peanuts.)
Wrong Parachute Gag: At one point in the second season, Brian is going skydiving. Right before he jumps out the instructor stops him and points out he grabbed "the one with silverware" in it. He tosses Brian another parachute... that clearly contains an anvil.
Wunza Plot: Parodied in the cutaway with Stewie and The Rock as partners. Also parodied in a deleted song (seen on the Vol. 5 DVD set) about a fictional sitcom called "Hope and Rape", about a former model and a former rapist living together.
Meg in the fifth season episode "Barely Legal". Meg in general for the last couple of seasons, really. Completelyjustifiedthough.
Also Quagmire's wife in the episode "I Take Thee, Quagmire".
Meg again in "The Hand That Rocks The Wheelchair", this time towards Joe, even going so far as to attempt to cripple herself for him.
Stewie, too, in the episode "Chick Cancer", where he burns his "wife" and her male friend alive in his playhouse.
Yes-Man: Lampooned in "Mr. Griffin Goes to Washington" when Peter gets his own company suck-up.
Suck-up: Morning, nice day!
Peter: It's a little cloudy...
Suck-up: It's absolutely cloudy, one of the worst days I've seen in years! So, good news about the Yankees.
Peter: I hate the Yankees.
Suck-up: Pack of cheaters, that's what they are! I love your tie!
Peter: I hate this tie.
Suck-up: It's awful, it's gaudy, it's gotta go.
Peter: ...I hate myself.
Suck-up: I hate you too, you make me sick, you fat sack of crap!
Peter: But I'm the president.
Suck-up: The best there is!
Ye Olde Butcherede Englishe: Peter names the bar in his basement "Ye Old Pube" after mistaking which word was supposed to have the "e" at the end in Old English.
You and What Army?: Because Peter's house wasn't in the town's map, he turned it into his own nation and named it "Petoria". Wanting respect from others at the United Nations, Peter invaded the United States. Namely, took over a neighbor's pool. In retaliation, the United States forbade any Petorians from entering American territory. When Chris told Peter a man didn't let him go to school, Peter asked he and what army and Chris answered it was the United States' Army. Peter said it was a good army.
Said to Peter after he tricks Dr. Hartman into giving him a flu shot that was in short supply and needed for the elderly. He responds with a reference to "Frampton Comes Alive."
Also by Brian when Peter tricks the Make-A-Wish foundation into bringing back "Gumble to Gumble" by pretending Chris has a terminal disease.
Brian to Stewie in "Brian & Stewie" when Stewie reveals that he made Brian eat his poop for a cheap thrill.
Brian:You son of a bitch, I could KILL you for that!
You Called Me X, It Must Be Serious: Attempted by Lois when a gun is pointed at her to get Peter to realize that something is wrong. Peter wonders why he is trying to comprehend this when he could be listening to his tapes in the car.
You Say Tomato: Stewie pronounces 'Cool Whip' as 'cool-huwip'. Brian tries fruitlessly to explain that it sounds weird, leading to Stewie using other w-silent-h words with the same weird pronunciation, totally unaware that he's doing it.
This becomes a minor plot point in one episode when Brian gets replaced by New Brain. Stewie begs Brian to come back and uses the "cool-huwip" shenanigans to get Brain to correct him, which Stewie missed a lot since New Brian is sickeningly sweet and doesn't hate anything.
Meg gets into it too, with the words "awhile" and "weird". The second is lampshaded by Brian: "Oh come on, that one doesn't even have an H in it!"
"It's all been 'ruweened'."
"Oh come on, Brian! Don't be cruwell!"
Stewie's shenanigans with words that have an "H" in it could also be chalked up to him doing it on purpose to get a rise out of people since he has said words like ruined normally.
Sort of. Stewie tells Peter that his death will be quick and painless when he changes the channel after Stewie got distracted by Teletubbies.
Flappy the pancake man. "Flappy, good news! I've decided not to kill you!"
Your Cheating Heart: There was an entire episode where Peter and Lois' marriage was about to fall apart because she slept with Bill Clinton (twice!). Granted, it did set up a funny joke at the end where Peter also ends up sleeping with Bill Clinton.
Your Mime Makes It Real: "Foreign Affairs" uses this in a gag regarding "mime on mime" violence in Paris; One mime holds up another, his finger pointing like a gun. After taking his victim's wallet, he "shoots", causing a wound to appear in his chest. After the victim drops, the crooked mime "shoots" him in the head twice, blowing it to bits.
