During the fight at the end of the episode, you can see Lois on top of the stereo throwing pictures at Peter, one of them being the picture of Stewie. Later in the fight, when Lois jams Peters head in a picture of a donkey, the picture is back.
As Brian talks about the idiots from New York coming, the toothpick and olive in his martini are on the left, but when it shows a close-up, it's on the right.
Before Meg destroys Chris' leaves, one is yellow and the other is red, yet they are both red when she destroys them.
When Stewie knocks out Peter with the baseball bat, the cookie box on the kitchen table disappears.
Peter is shown eating a graham cracker, but the box in front of him is a cookie box.
(New York priest walks up to podium)
New Yorker Priest:Yo! God is good ehn? And he expects us to be good. And if you're not, he's gonna come down, and bust your freakin skull! Amen.
Diane: Good evening, tonight's top story, Quahog is infested. With loud hairy creatures also known as New Yorkers.
Brian: What about the "writing angry letters and not sending them" exercise?
Peter: Aw geez, I wasn't supposed to send those?
Meg: Look, I got a letter from dad! Dear Meg, for the first four years of your life, I thought you were a housecat. Dad!
Stewie: Dear Stewie, get out. Oh, that's nice.
Lois: Mine just says Dear Lois, and after that it looks like someone just spit on the paper.
(Meg and Chris are raking leaves)
Chris: Hold it, Meg. Those two are mine.
Chris: That's Randy and that's Fred. Randy's the messy one. Fred's very neat. And when you get them together, whoa! Hold onto your sides!
Meg: Nice to meet you both.
(Meg picks up the leaves and rubs them together)
Chris: (gasps) Murderer!
(Chris chases after Meg and they get caught by Lois)
Lois: Stop it! Both of you! Starting now, you two are gonna love each other.
(Lois makes them hug)
Lois: Now stay that way!
Chris: It's gonna be weird to potty.
(Lois and Stewie at the swings)
Lois: Excuse me, we were about to use that.
Lady: You snooze, you lose, lady.
Lois: You have 2 choices. Either my baby swings from this jungle gym, or you do.
(Lady walks away and Lois puts Stewie on swing)
Stewie: Woohoo, Lois! Someone's wearing their ovaries on the outside.
Lois: She saw me walking to the swing.
(Lois begins pushing Stewie on the swing too hard)
Stewie: Yes, Yes. She saw you. Easy now.
Lois: And nobody walks all over me! Those days are over! Lois Griffin demands respect!
(Lois pushes hard and Stewie flies off the swing)
Stewie: I know you not putting that rock up from here. You ain't got no J.
(Stewie trips player)
Player: Yo man! That's trippin'!
Stewie: Please! You're the one who's trippin'! Go on! Cry home to yo' momma. She waitin' for ya!
Player: Don't make me put my size 13's up your narrow ass!
Stewie: I don't sweat you. Bring it on, bitch! Now, how ya gonna act?
(Player walks away)
Stewie: Huh, Bring that trash in here. This my house!
(the family is stuck in traffic)
Lois: We're gonna be late for church.
Peter: MOVE IT! Damn leafers.
Meg: Chris, quit it! Mom! Chris put his foot on my side again!
Chris: I can't help it. I have these long dancer's legs.
Meg: Move it!
Stewie: Meg, stop your whining. Chris, stay on your own side. Lois, for God's sake, get off your ass and do some parenting!
Lois: If you kids don't knock it off, we're not goin' to McDonald's after church.
Meg and Chris: MOM!
Peter: Don't worry. We're goin'.
(Lois glares at him, then Peter turns back to the kids)
Peter: B-B-But you don't get the Supersize.
Peter: Okay, you can Supersize. But no apple pie!
Meg: Oh, come on!
Peter: Okay, you get an apple pie, but you can't blow on it.
New Yorker #1: Yo, Maddie! Check out those colors. Yellow like a taxi, orange like the ball at the Knicks game, and red like the sauce on my Mama Mia's gugaz.
New Yorker #2: And brown, like the guys I don't pick up in my cab.
New Yorker #1: Beautiful!
Bonnie: Oh, the baby's kicking. Wanna feel?
(Peter puts his ear to Bonnie's stomach, and the baby kicks him in the face)
Peter: Oh, you are dead kid!
Peter: (To Bonnie) Boy, you must've had a pretty good body before it went all funhouse mirror on you.
Quagmire: Hey baby, how about showing me your Lower East Side?
Quagmire: Whoa, transvestite! Wait a moment, pre-op or post-op?
Quagmire: Whoa, transvestite! Back off!
Stewie: (imitating Brian) I'm the dog! I'm well-read and have a diverse stock portfolio, but am not above eating grass clippings and regurgitating them on the small braided rug in front of the door.
Brian: (imitating Stewie) I'm a pompous little anti-Christ who will probably abandon my plans for world domination when I fall for a rough trick named Jim.
(after Lois defeats her Martial Arts Instructor)
Peter: Lois that was amazing! Congratu-.(gets cut off when Lois kisses him aggressively)
Lois:(Breaks kiss, then grabs Peter's crotch)This is mine! This is where my babies come from!
Peter: Jets suck! Yankees suck! Knicks suck!
Peter: Excuse me, is your refrigerator running? Because if it is, it probably runs like you - very homosexually.
Peter: Don't worry, I got an idea. An idea so smart my head would explode if I even began to know what I was talking about.
Peter: Look at all the garbage the damn Leafers are dumping on our lawn. The New York Post, New York Magazine, the New York Mets.
Lois kicks the girl who takes away the football. This is a reference to Peanuts, the popular Charlie Brown comics and TV Show, where Charlie would start running to kick a football being held by Lucy and then Lucy would pull it away as he was kicking it, causing Charlie to fly through the air and fall down.
Do The Right Thing
Peter: Lois, brothers and sisters fighting is as natural as a white man's dialogue in a Spike Lee movie.
Peter is referring to the movie "Do The Right Thing."
Peter: Why the hell doesn't the government step in and tell us what we can and can't watch?
This refers to the television show ratings that were established in the United States in the mid-1990s. These were created so that parents could monitor what programs their children were viewing and make sure those programs were safe for them. The six ratings are: TV-Y (viewable for children of all ages), TV-Y7 (viewable for children over seven), TV-14 (viewable for people fourteen years and older), TV-G (viewable for all people), TV-PG (parental guidance suggested for child viewing), TV-M (mature audiences only, more or less for viewers seventeen years and older (this rating was later renamed TV-MA)). There are also signs included with each rating to indicate what content was in the show (there aren't any included with TV-Y or TV-G ratings, as these shows have no suggestive content): FV (fantasy violence (only included with TV-Y7 ratings), D (suggestive dialogue (not found with TV-MA ratings)), L (adult language, be it mild or strong), S (sexual or sex-related situations), and V (violence, be it mild or strong).
Peter: Krypton Sucks
The three bad guys from Superman II (General Zod, Ursa, and Non) were hanging out in the bar and got called out when Peter was naming teams from New York that suck.
The Karate Kid
Peter: Hey Ralph Macchio!
Peter calls the Tae-Jitsu teacher Ralph Macchio. Ralph Macchio played Daniel LaRusso in The Karate Kid, in which he learned karate to defeat the bullies who were picking on him.
The title is a reference to the Lethal Weapon movies.
Peter: She floats like a butterfly and stings like when I pee.
Muhammad Ali (AKA Cassius M. Clay) was a boxer who used to say he "floats like a butterfly, stings like a bee."
Lois: This is mine... this is where my babies come from.
During the OJ Simpson Murder Trial it was reported that one night in a bar OJ grabbed his wife's crotch and made that same announcement.
Mad Max Beyond Thunder Dome
Lois: Spin the wheel Raggedy Man!
Lois says this before fighting her Tae Jitsu instructor. In Mad Max Beyond Thunder Dome, Tina Turner's character Aunty Entity refers to Mel Gibson's Max character as "Raggedy Man." The movie also contains a scene where Max is spun on a giant wheel to determine his fate.
