Lindsay has a "Dennis Kucinich for President" bumper sticker on the back of her car.
Goof: As Lindsay and Ryan pull up to the Cohen's driveway, we can see that Lindsay has many bumper stickers on her car. These include "PeTA", "Kerry & Edwards", "Free Tibet", "Extinct is forever" and others.
Goof: At the 39-40 minute mark, Seth bends over to look under his bed to see if Summer took his comic book drawings. When you see him bend down, he puts his right hand on the floor to give him stability and from another angle it is his left hand on the floor, and back and forth.
Goof: In the scene in Seth's bedroom with Seth and Summer, there is a white fluff on the back of his sweater that appears and disappears between shots.
Goof: Ryan told Lindsay the reason that he was late getting to the restaurant was "traffic" as if he drove himself there, but then later they showed Lindsay driving Ryan home as if he didn't have a car. Perhaps he took a cab?
Summer: I don't wanna hear it. What are you guys? Like Kavalier and Gay?
Seth: That was funny.
Summer: I know.
Ryan (to Caleb about Lindsey): She's been asking questions about you. Who you are, what you're like. And even though I told her, she still wants to get to know you.
Marissa: What are you doing in here?
Caleb: You're not at school.
Marissa: Yeah, you're not at work.
Seth: I know that it's totally creepy. I know that. I'm sorry. It was just a very long summer and I'm sorry and I will destroy all of them right now. I just need to find my X-Acto knife.
Max (surveying Sandy's new office): I was under the impression you'd become a successful lawyer.
Gail: As you can see, it's a bit of a fixer-upper.
Kirsten: That's one way to put it.
Sandy: Who are you kidding, Gail? This place is a first-class dump. And I like it!
Zach: You should just focus on the good stuff in your life. Like school. (Seth grimaces.) Or... comics. Yeah, I got nothing.
Summer: I mean well, the boobs are a little big, but well I mean, aren't they?
Seth: I can redo the boobs, so then you don't mind?
Summer: No, not as long as I have boob-approval.
Summer: If Brainstorming boy here doesn't turn back into my boyfriend.
Seth: Brainstorming boy, brainstorming lad, let's work with this, brainstorming kid, brainstorming young ward, with a secret identity which is at night, he's brainstorming man and what that is is he's a genius.
Ryan: So what's it about?
Seth: Oh... eh, heroes, and you know villains...
Zach: Good and evil!
Seth: Darkness and then you have light.
Ryan: You guys have no idea, do you?
Seth: Um not so much really but you have to admit, it's pretty exciting our very own comic book.
Marissa: I have a mom who is spa-hopping and a stepdad who doesn't care about anyone but himself.
Seth: Do I hear water running?
Alex: Yes, Jody's taking a shower.
Seth: Oh, Jody..., Jody is still here, oh, that's great, that's fantastic, at least you're not taking a shower together.
Alex: Doesn't anybody go to school anymore?
Zach: So you never had like a moments doubt about you and Lindsay?
Ryan: Not really.
(Seth mutters "denial" and coughs)
Ryan: Alright there may have been a moment.
(Seth coughs louder)
Ryan: Or two.
Ryan: How did it go with Zach?
Seth: Ah, great until Summer came over and stole my sketchbook.
Ryan: What! What did she do?
Seth: I thought she was going to get a restraining order but turns out she's just going to get her own action figure.
Marissa: You're not my father Cal. If you want to parent someone why don't you go over to Lindsay's house and ruin her life. Oh you already have!
(Marissa rejects Caleb's attempt to control her.)
Ryan: You should call him.
Lindsay: And say what? Hi, dad, it's your illegitimate daughter. Want to have lunch?
Alex: Sorry, I would have introduced you guys but I didn't want you to meet.
At the beginning of the episode Seth knocks on Alex's door. Alex answers and hearing the noise, Jodie comes out of the bedroom.
Seth: (about Ryan's comicbook identity) Hey, Bryan Gatwood, AKA Kid Chino, a strong but silent youth from the wrong side of the tracks, who when provoked unleashes his fists of fury.
Lindsay: (about Caleb) According to the OC Weekly, he's pretty much everything that's wrong with western civilization, all wrapped up in one guy.
Caleb: I haven't always been the best father.
Kirsten: Pretty much... No.

Lindsay: "I A9.com'd him last night, and according to the OC weekly, he's pretty much everything that's wrong with western civilization.."
Lindsay "A9.com'd" Caleb, which means she did a search at A9.com for his name. A9.com is a new search website, with some cool features.
