Peter actually started out in this territory. Despite always being selfish to a certain extent, he would often learn from his mistakes at the end of each episode. After the show was brought back, though, he was turned into more of an outright sociopath.
A cutaway concerned a "badass mail clerk with a heart of gold."
Peter: Hi, Kenneth. Hey, did I get any mail?
Kenneth: No! And if you come any closer, I'll slice ya!
Peter: (to a co-worker) Jeez, what a badass.
Guy: Yeah? Well that badass just gave half his paycheck to orphans, orphans with diseases. (Peter nods appreciatively)
Jerkass: Most of the cast and characters, although some characters shift into Jerk Ass territory more than others.
Jerkass Ball: Every character has moments as one based on Rule of Funny in later seasons. Even Lois and Brian, who by default are somewhat straight-faced and fairly empathetic characters, can become selfish, vindictive, and outright sociopathic jerks if it helps with the shock value comedy.
Jesus: The Early Years: An episode shows him as a teenager, trying to deal with God being an absentee father who's shacked up with a bimbo.
Jesus: Uhh, Hey dad, so um.. Things aren't working out too well here. Can I come stay with you for a while?
God: Gosh, you know, I'd love to, son, but this isn't a very good time right now. *Hangs up, and returns to the whore in his bed* God: Alright then, now where were we?
Girl: Right about here. *Holds up a condom* God: Aww come on baby, it's my birthday! Girl: No.
Jitter Cam: Used very noticeably each time an airplane was on a collision course in "Airport '07".
Al Harrington of Wacky Waving Inflatable Flailing Arm Tube Men Emporium.
When Peter becomes one of the New England Patriots, he does a local spot for a car dealership complete with monotone reading, eyes following cue-cards, forced football references, and crappy redundant jingle.
Sonja, Quagmire's ex-girlfriend from the season 12 episode Quagmire's Quagmire was also one of these. She humiliates Quagmire in public, beats him over the head and puts him in the trunk of his car, fully intending on making him into her sex slave.
A good one happened to Connie D'Amico in the episode "Stew-Roids". Connie rebuffs Meg when she tries to give her a High School Musical soundtrack and insults her. One Jerk Jock farted in her face and had Meg running off crying. As soon as Connie started dating Chris and then Chris has a party at his house, he is caught making out with other girls and then dumps Connie. Connie then becomes unpopular and when Connie tries to get help from Meg, Meg coldly tells her off. Subverted in that Meg decides to help Connie make Chris become unpopular again, and then Connie goes back to being popular and disliking Meg.
In one episode Stewie abducts the cast of Star Trek: The Next Generation after he's unable to get his questions about the show answered at a convention. After he kills Denise Crosby to make sure they don't try anything funny, he spends the day with them, only they turn out to be totally annoying and demanding. By the end of his time with them, he's announced that they've ruined Next Generation for him and he hopes they all die. Alternative Character Interpretation: One could argue that the cast were acting this way on purpose, seeing as how he killed Denise, they probably figured that by acting utterly annoying he'd grow sick of them and send them home. Counts as either a Batman Gambit or Thanatos Gambit, because if such was the case, there was just as much chance he'd kill them if they annoyed him too much..
"PTV": Stewie supplies his own exaggerated laughter (and applause) for the low budget sitcom "Cheeky Bastards".
"Airport '07": Peter doesn't want to kick Quagmire out of their house, until Quagmire mentions that Stewie should never use a pacifier that he's holding again. Peter says to Lois, the "OK, so I'll talk to him tomorrow?", followed by a laugh track and a parody of the Will and Grace eyecatch.
"Chick Cancer": A cutaway gag features "The Mayor of Comedy" pitching a Time-Life Music-type compilation called "Sitcom Punchlines of the '80s," with one of the volumes titled "Sounds of the '80s: Studio Audience," that volume being various canned studio and "laugh track" responses to stock jokes and cliches. (The albums were also a parody of various Time-Life Music series, one of which was "Sounds of the Eighties.")
Left It In: When Brian joins The Bachelorette, he makes some comments about Chevy Chase to the Confession Cam and then asks if they can cut that part out…and then goes on to say even more things about Chevy.
Lethally Stupid: Peter Griffin. Just try to make a kill count. Many characters in the cutaway gags are this.
Let's Have Another Baby: After assisting his sister-in-law in giving birth, Peter first suggests stealing her baby, but then says this to Lois who agrees. That is, until they realize that they're too busy with Stewie to take care of another baby.
Let's See You Do Better: In "Brian Griffin's House of Payne," at the premiere party of Brian's new sitcom, the cast of Two and a Half Men are also at the party, much to Brian's surprise. When asked why they're here, Charlie Sheen responds, "Well you're always ripping on our show, let's see yours."
Peter: How many dirty, stinking apes does it take to screw in a lightbulb? Three; one dirty, stinking ape to put in the lightbulb, and two dirty, stinking apes to throw feces at you.
Limb-Sensation Fascination: One episode has Joe Swanson gets new functional legs transplanted, and he proceeds to show off his old athletic and martial arts abilities to the point of becoming arrogant and rejecting his old friends for new ones who can keep up with him. In the end he becomes paralyzed again in An Aesop about pride.
Limited Animation: Taken to extremes post-cancelation. Lampshaded like almost everything else at one point.
Lint Value: When Peter and Lois are buying fake documents on the Black Market in Cuba, Peter realizes he has no money and asks the cashier if he will accept bits of string instead. The cashier replies, "Sorry, store policy" and points to a sign noting... that they don't accept bits of string.
Littlest Cancer Patient: Poor, poor Abbie, Quagmire's five-year-old niece. She makes an appearance in "Road to the North Pole", and Brian mistakes her for a boy because she lost her hair from chemo.
Locked in a Room: "Brian & Stewie", where the duo is stuck in a bank vault all night.
Logic Bomb: Peter does this to a robotic office suck-up that agrees with everything he says to try to make him stop:
Peter: ...And 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! Peter: But you just said you hated me... Suck-up:(malfunctioning) But—not you the president—that you who said you hated—you, you who love—hate... Yankees... Clouds...(head explodes)
Most famously, after the series is brought back, Peter recites a long list of Fox programs that bombed while Family Guy was off the air, sarcastically calling them great shows. He then goes on to say that maybe Family Guy can come back on the air if every single one of them fails. A similar gag was used in "Family Gay" with race horses named after cancelled Fox shows with the announcer telling their positions.
Also on "Episode 420," Peter gets so high that, instead of setting up one of his flashback moments, he shows the viewers a list of celebrities he hates, including Stephen Dorff, Justin Timberlake, Dane Cook, Chris O'Donnell, Geoffrey Chaucer, Kathy Griffin, Andy Samberg, Elisabeth Hasselbeck, Andrew McCarthy, Rita Coolidge, David Arquette, Carlos Mencia, Amy Winehouse, every rapper, Ethan Hawke, Dax Sheppard, Toby Keith, Joe Francis, Princess Diana, Chris Martin, Chris Martin again, Chris Martin's parents, Eve Plumb, Bonnie Franklin, Kate Bekinsale, Freddie Prinze Jr., Suri Cruise, The forehead guy from The Office, Garry Marshal, Paul Tsongas, and Chris Martin's ancestors.
In "Ocean's Three and a Half" Stewie writes a song for Susie named after her. Brian sarcastically comments thats the first time a song has been named after a girl. Stewie asks him to mention 20. Then 6 more. Then 5 more. Then he storms off.
Quagmire's "The Reason You Suck" Speech to Brian. Supporters call it a long overdue callout to Brian that outlines exactly why he's considered a Creator's Pet, while the detractors claim it's pure hypocrisy given that Quagmire...isn't exactly a pillar of morality himself (which he slightly acknowledges in it...).
Longest Pregnancy Ever: Bonnie was pregnant in her third trimester for a full ten years and six seasons after her introduction. Lampshaded by Peter in one episode:
Peter: Okay, first of all, Bonnie, you've been pregnant for like six years, alright, either have the baby or don't.
Loud of War: In the Star Wars spoof "Laugh It Up, Fuzzball"', the torture scene from Empire is recreated with Han (Peter) being tormented by "Where Have All the Cowboys Gone?"
Mama Bear: Lois, despite the nastiness she's increasingly showed, is seriously this when it comes to Stewie. Willing to fight a vicious dog to get his teddy bear back. Making the mother of the older bully kid who stole Stewie's Halloween candy give it back plus the bully's candy plus forty dollars! (At 100% interest, compounded daily; when the woman nervously tells Lois she doesn't have forty dollars, Lois tells her that she'll be back the next day for eighty dollars. God only knows what Lois will do to her if she doesn't eventually cough it up. She even scares Stewie with that.)
Subverted at first and then ultimately fulfilled when she tries to save Joe from falling down a sewer waterfall.
Lois: I can't hold on, Joe!
Joe: Pretend I'm your child, Lois! (Lois starts to let go) Not Meg, not Meg! (Lois finds the strength to pull him to safety).
At the end of "Meg and Quagmire" after she and Peter stop Meg from having sex with Quagmire, she threatens to cut his "thing" off and feed it Brian. *Shudder*
Mediation Backfire: Peter is upset that he can't find way to bond with Stewie, until he discovers that beating up Lois is the perfect way to do it. Crosses the Line Twice when they lock her in the trunk of a car and sink it in a lake.
Seen in "Road to Rupert" during the Stewie/Gene Kelly dancing sequence, which combines live action and animation.
Also seen in "Let's Go to the Hop" when Peter said that doing drugs caused things to get too real for him, and the show cutaways to a live action Peter on a park bench saying: "Holy crap, I am freaking out!"
They use puppetry in "Foreign Affairs".
Men Can't Keep House: Appears in an episode where Lois went to jail. After being arrested the house goes to hell, with garbage all over the place, Stewie not getting a diaper change in god-knows-how long, and wild animals coming into the house.
Mid-Battle Tea Break: When Brian and Peter rescue a talking cow, they're chased by 2 guards. The Montage show them all in a band, playing music together.
Chris was once really just using the bathroom, but his Holier Than Thou grandfather assumed he was masturbating and railed against its sinfulness, scaring poor Chris away from what he was really doing for the rest of the episode. "God's watching me do Number Two? Aw man, I'm a sinner and God's a pervert!"
In a pre-cancellation episode, after Chris is caught peeping in the girls' locker room, Peter approaches Chris' room, and there's a rapid knocking sound, which turns out to be Chris, playing with a ball-and-paddle. Peter gives Chris his porn collection, then leaves, and the sound continues, then Peter realizes he's holding the paddle
Monkeys on a Typewriter: Peter references them in "The King Is Dead". In a twist, the monkeys are fully intelligent and speak exactly like regular humans.
Dr. Hartman's conversation with Peter and Brian over a much needed kidney transplant. He tells Brian that because his kidneys are smaller, Peter would need both of his in order to keep living. He tells Brian that the procedure would kill him... Then he laughs as he notices a car being towed outside.
In "Brian Wallows and Peter's Swallows", there's a big mood whiplash after Brian tearfully says goodbye to a dying Pearl. Immediately after, Dr. Hartman comes in and says, "Hey, anybody wanna see a dead body?"
Moon Landing Hoax: "Don't Make Me Over" has a Cut Away Gag that shows Neil Armstrong finishing up the filming of the moon landing, then walking out back of the studio to head home. A fan recognizes him and questions why he isn't up in space. Neil nervously tries to make up an excuse before panicking.
Neil Armstrong:Oh, uhh, there was a tape delay, and uh solar winds and... (Bashes the guy with his space helmet.)
Motivation on a Stick: In "He's Too Sexy for His Fat", Peter gets Chris to run on a treadmill by sticking a plumber's helper to his forehead with a twinkie hanging from it.
Mundane Afterlife: In Stewie Griffin: The Untold Story, Stewie briefly dies and goes to Hell, which is nothing more than an ordinary hotel room. At first, Stewie doesn't think it's so bad, but then Steve Allen comes in, unbuttons his shirt, and tells Stewie, "All right, let's do this." It turns out Steve wasn't actually going to have sex with Stewie, but then Steve turns on the TV in the hotel room and the programming is nothing but Who's the Boss? reruns.
Herbert's fight with Mr. Gutentag in order to save Chris and Peter. The fight itself is extremely awkward, but the music was epic and Gutentag's death was just a fall from a porch, but the camera angle and slo-mo really invoked this trope.
Pest extermination got this treatment in season 3's "He's Too Sexy For His Fat", making a standard extermination job look like a scene from The Expendables- nearly ten years before said film was released.
Murder by Mistake: In the 9th season premiere, Diane's mechanism to murder James Woods accidentally kills Stephanie.
Mushroom Samba: Brian consumes psychedelic mushrooms in "Seahorse Seashell Party", and ends up having a series of horrifying visions.
The Musical: The whole show. Random and lavish show tunes are a regular occurrence.
Mustache Vandalism: Parodied in "Love Thy Trophy". As Peter ransacks his neighbors' houses to find their supposedly stolen Trophy, he paints mustaches on each of their family portraits, and rubs out Cleveland's already existing mustache on his.
Stewie isn't an animal, but despite being more intelligent than anybody else on the cast, he still has many natural baby instincts, such as loving Teletubbies and going ballistic when he finds out they're going to Disney World.
My Sibling Will Live Through Me: In "Go Stewie Go", Stewie pretends to be a girl named Karina Smirnoff in order to land a part on the American Adaptation of his favorite television show - the only part available was playing a little girl named Mary. He then falls in love with one of his (female) costars, but the costar explains to her/him that she's not a lesbian ... so Stewie marches into the (conveniently live) taping of the episode, and in character (as Mary, not Karina/Stewie) explains that Karina was actually his sister who died, and he was Desmond - a perfectly normal little boy transvestite - who was trying to carry on her memory.
In "Baby, You Knock Me Out". Throughout the episode, people are surprised that Lois can fight so well and that she can be so aggressive, including Lois herself. Lois even says something to the effect of how she's never felt so powerful. She has, however, in episodes like "Lethal Weapons" and "Breaking Out Is Hard To Do".
In "The Fat Guy Stranger" (airdate- 2005) Lois revealed she was in her forties. "Meet The Quagmires" (2007) revealed Lois was 18 in 1984. "And I'm Joyce Kinney" (2011) revealed she legally starred in a porno film in 1981.
Nested Story Reveal: As it turns out, all the events of "Stewie Kills Lois"/"Lois Kills Stewie" was just a simulation that Stewie was running to see what would happen if he succeeded in his plan to Take Over the World.
Never Bareheaded: Meg and Chris usually wear their hats. Meg is especially notable: going hatless appears to be akin to nudity for her (she quickly covers up when discovered brushing her hair, and a makeout fantasy has her inexplicably hatless).
Brian once dated a Brainless Beauty and was conflicted about it, however everyone (including Quagmire, who also dates brainless beauties) accuses Brian of only dating women for their looks (even though Brian once dated Rita, an elderly woman).
Lois was in a porno but she learned to live with that and showed the video IN CHURCH.
Priest: "I may be a man of God, but THAT SHIT IS HOT!!!"
Never Trust a Trailer: Done a lot in later seasons, especially with episodes featuring an A-Plot with Meg or Chris and a B-Plot with Brian and Stewie. The promotional image for "Not All Dogs Go To Heaven" was Stewie with the ST:TNG cast, as well as the summary. Six minutes into the episode, Peter announces that it's going to be a Meg Episode (although in the end it was more about Brian). The Star Trek cast got like one or two lines each. Another similar example is "Stew-Roids". All the promotional images and summary were about Stewie muscling up, and implied that the story involving Chris, Meg, and Connie was a minor subplot.
In "Road to Rupert" after Meg had enough of being humiliated by Peter and his friends, she stops the car she's driving them in and immediately gets rear-ended. When confronted by the hostile driver of the vehicle behind her, she proceeds to beat the guy.
In "Dial Meg for Murder" Meg comes out of jail as a hardened psychopath and gets revenge on her abusive family and classmates. In it she beats the crap out of Peter twice and beats up the popular kids with a pillowcase full of unopened sodas.
In "Quagmire's Dad", Quagmire administers a brutal beat-down to Brian after he finds out that Brian had sex with his father, even though Brian had no idea.
"Peter's Daughter"; "Hey Connie. Hi. I'm Peter Griffin, Meg's father. Say could you do me a favor? Ya see that fire extinguisher over there?..."
"The Hand that Rocks the Wheelchair": every murder committed by Evil Stewie.
No Product Safety Standards: Peter falling asleep on the job at the toy factory allowed dangerous products to ship; such as a bottle of pills inside a "Pound Poochie" box, a "silly ball" being a throwing hatchet, and a girl's doll being built in with a flamethrower.
No Such Thing as H.R.: The Pawtucket Brewery. The plot of one episode has Peter's boss Angela sexually harassing him; never once does Peter even consider taking it up with HR. (or even if the company has HR).
Non-Specifically Foreign: The two long-haired blond guys first introduced in a cutaway about people whose English is just off enough that you can tell they aren't native speakers, but not bad enough to reveal where they're from.
Lois: Peter, what the hell?! You can't bring that horse into our bed! Peter: Lois, I can not believe you would ban the horse from our bed. He's a graceful, majestic creature, who is a part of this family and only wants you to love and respect— the horse may have pooped in the bed.
Not Quite Dead: Meg, Ernie the Giant Chicken, Connie D'Amico, and the Evil Monkey have all been left for certain death and somehow survived it.
Referenced in a cutaway in an early episode involving Peter's ancestor Huck Griffin who now referred to his raft partner as "N-word Jim".
When Peter thinks the world was going to end, he mentions that he is going to go to the black section of town and say the N-word. He returns a short time later wearing a sash that says "King of the Black People," and says "They respected me for saying it."
Lois has a terrifying one when she realizes that Diane Simmons is the killer at James Woods's mansion.
Stewie and Brian say this when they realize their hands have been perma-glued together.
Older than They Look: One one-off joke shows Quagmire is actually in his 60's, despite looking younger than that. What really makes this odd is when Quagmire's dad shows up, and he's the one who looks to be in his 60's, especially since he served in Vietnam.
Narrator: In the television comedy world, the people are entertained by two separate yet equally important types of shows: Traditional sitcoms that get laughs out of everyday situations, like trying to fix your own plumbing or inviting two dates the same dance, and animated shows that make jokes about farting. This is the latter.
Out-of-Character Alert: Lois tries one with Peter when Diane points a gun to her back, without success. It's even lampshaded: Peter, we are married for 24 years, notice that something is wrong!; Strange, she has never called me Pete. Nevermind..
Out of Focus: Since the show returned, Lois, Meg, and Chris only get one (sometimes two) episodes per season focused on them, while the rest of the season being focused on Brian and Stewie, and to a lesser extent Peter.
Peter: That's right, it's going to be a Meg episode. (places remote on the table) Here's the clicker. No one'd blame ya.
Meg has been hit with this the most. It's to the point that, even in an episode where Meg is the driving force of the plot, she disappears entirely after the first five minutes, does not reappear until five minutes before the end and spends three of those being entirely silent.
Overcrank: Parodied, with most anything else, in "The Kiss Seen 'Round the World": Meg swoons over Tom Tucker, who is walking in slow motion. It's assumed that he's only walking in slow motion in her fantasies, but no, that's how slow he actually walks, and people around him walk normal speed.
Overly-Long Gag: A self-admitted favourite of series creator Seth MacFarlane. Opinion is constantly divided over whether such gags make the show better or worse.
Overly-Long Scream: Peter does it when the experimental drug that temporarily turned him gay wears off in the middle of a group sex session. Also his shriek of acclamation when the drug first kicks in and Lois asks if he has turned gay. Also when his doctor performs an intimate anal examination.
In "Forget-Me-Not" Peter finds a jukebox playing "Surfin' Bird," and turns it off because he finds it annoying.
In "Family Goy", when Quagmire believed he was getting the spinoff instead of Cleveland, one of the things he admits he's not going to miss are all of the stupid Conway Twitty jokes.
Palette Swap: Lois' sister, Carol, is practically a copy of Lois, the only difference being the clothing and the hair.
Paranoia Gambit: Done successfully by Brian in "Patriot Games" when Stewie, as payback for the brutal beating he gave Brian over the money that Brian owed him, offers Brian a free revenge shot. Brian agrees on the terms that he can use it at any time and that Stewie won't know when he will be hit. Brian does not use it, and Stewie goes crazy to the point of harming himself to even the deal. At the end of the episode, Brian evens it out by pushing Stewie in front of a moving bus. Also doubles as a Crowning Moment of Awesome for Brian.
Parking Payback: In the first Christmas episode, Peter gets fed up with searching for a parking space at the mall and just drives onto another car, crushing it like a monster truck.
Parental Incest: Oddly enough, One of the few things NOT poked fun of. Couple of examples would be the "incest episode" Peter mentioned after the Untold Story movie, and Meg getting yelled at by the family for making an incest joke.
Except for Peter who giggles afterwards.
There's also this from Peter's redneck phase in "Airport '07".
Peter: Meg, I'm a redneck, which means I am about to do something to you that you will not remember until you're forty! (Meg screams and runs off) Meg, come back here! I meant sex!
Meg's bachelorette party, where Peter was the stripper.
When Chris proposes her to Peter to date in the same episode.
Paying In Coins: Done in an episode where Stewie is held up in line in a supermarket due to Bruce, after done quibbling over having one item over the 10 Items Or Less limit, asks to pay for it all in pennies.
Personal Arcade: In "Stewie Griffin: The Untold Story", Peter gets Lois a Galaga arcade machine for Christmas.
Pet the Dog: Both Stewie and Quagmire have certainly had moments where they have done this.
Phony Degree: "When You Wish Upon a Weinstein" involves Peter taking Chris to Las Vegas for a quickie Bar Mitzvah, in the expectation that converting to Judaism will make Chris smarter. (Not a degree per se, but a genuine Bar Mitzvah involves scriptural studies.)
Pictorial Speech Bubble: In an episode, when Lois revealed that her wealthy father offered them a million dollars after she and Peter were newly married, but she turned it down because "they could make their own way", Peter has a thought bubble containing an animation that showed him killing Lois rather violently.
Pie in the Face: Lois (twice if you count "Saggy Naggy") in "You Can't Do That On Television, Peter," and Herbert in the "It's a Wonderful Day for Pie" sequence in "Road to the Multiverse."
Pineapple Surprise: Used in the climactic battle in "Lois Kills Stewie", though she is able to remove the belt before the explosion.
A Pirate 400 Years Too Late: Peter goes from stealing a parrot as a pet from a veterinarian's office, to dressing as a stereotypical pirate, then hiring a pirate crew and finally going on the road and engaging a motorist in an epic swashbuckling fight, in the course of which Peter's car acquires a mast and sails.
Planet of Hats: Played straight in "Road to the Multiverse". Each universe that Stewie and Brian travel to has it's own special attribute; there's the universe where humans and dogs switch places, and then there's the universe where there's just one guy who gives compliments from far away.
Peter: Stewie, uh, how long you been all messed up and evil like this? Stewie: Oh, so now you're interested in Stewie. Last week when I made that macaroni picture of an owl, you didn't give a damn! Peter: That was an owl?
Plot Hole: A big one that is attributed to Brian being the Author Avatar. Brian is an Atheist despite meeting God AND Jesus on several occasions.
Chris identifies a store robber after being assured that he is perfectly safe. Then Peter walks in.
Peter: Hi. Excuse me, you guys. I'm here to pick up my son, Chris Griffin. He's here to finger the guy who held up that convenience store. Maybe you've seen him. His name is Chris Griffin. I think I got a picture of him, somewhere. Here you go. Yeah, you can go ahead and hang on to that. I got a ton of them at home. In fact, I was gonna throw that one out anyway, 'cause Chris messed it up by writing his school schedule and a list of his fears all over the back of it.
A Cutaway Gag had Peter ask certain people in the line-up to step forward, then act out various improv acting scenarios "Ok, pretend like you haven't seen Number 3 in a while and are really glad to see him!"
Poor Man's Porn: When Stewie finally succeeds in derailing Peter and Lois' plans to conceive a fourth child (about twenty seconds after he stops trying), Peter takes a lingerie catalogue into the bathroom.
Positive Discrimination: Subverted in "Extra-Large Medium" where a girl with Down's Syndrome is portrayed as a bitch.
Peter tells America to go fuck itself in Stewie Griffin: The Untold Story.
In "Peter's Two Dads", Brian says, "What the fuck?!" when he sees Peter on the couch, who just got done taking crack.
In the DVD version of "Friends of Peter G", there's this upon Peter's discovery of himself without alcohol:
Peter: Who the fuck is this queer?
Previously On: Parodied and subverted at the start of "Brian Does Hollywood". All of the clips shown never actually occurred in part one, "The Thin White Line", and instead are send-ups of typical crime and court drama tropes.
Stewie: You want my badge number? Here! Here's my freakin' badge number!
Product Placement: Done by Stewie for an in-universe joke shop in season Three's "Lethal Weapons". "That's Jack's Joke Shop. Remember, if it ain't funny, it ain't worth Jack. He plugs the same joke shop in season Five's "Road to Rupert", to Brian's unamusement.
Lois mentions Stop & Shop (an actual Northeastern based supermarket chain) in the pilot.
