As of this episode, Rachel Bilson (Summer Roberts), and Melinda Clarke (Julie Cooper) appear in the opening credits, not as guest stars.
Goof: Ryan and Seth seem really distressed to be stuck in the pool house on New Years Eve, however they do not really make an effort to get out, and of course there is no spare key or phone in the pool house that they could use.
Goof: At minute 6-7, just after Seth says: "I'll do whatever Ryan and Marissa do.", Ryan is looking at Seth and Hailey, then when the camera angle changes Ryan is looking at the cupboard.
Goof: In the opening "I love you" scene between Ryan and Marissa, when the camera is on Marissa her arms are to her side. When the camera is on Ryan, Marissa's hands are on his chest. What results is an "up/down/up/down" kind of thing.
Goof: At Oliver's party, Summer says "Seth Cohen is so 2003, and in 74 minutes I will never have to think of him again", then Anna says "73". That would make it one hour and 13 minutes until New Year's. But when Summer says this Sandy and Kirsten aren't even at their party. They skip their dinner reservations which are at 8:30 and head straight to the party. How could it be before 8:00 if there is 73 minutes until New Year's?
Goof: Seth and Ryan get soaked with champagne, but in the next scene they are still wearing the same clothes, which are clean and dry.
Goof: The green lime in Marissa's drink moves from being to the top of the glass to the middle, when the shot changes from wide to close-up.
Goof: Both Ryan and Anna have the same distance to cover, going in opposite directions. The former from the Cohen's to the hotel party and the latter from the hotel party to the Cohen's. Ryan leaves before Anna and yet she arrives considerably earlier. The traffic might have slowed Ryan slightly, but not to that extent.
Kirsten: Seth! Garbage. Out. Now!
Sandy: I have two reasons, either she ran out of money, or, she ran out of money.
Seth: Three letter word for hilarious: Dad. Write that one down.
Hailey: You know, it's too bad that you're busy tonight. 'Cause I know this really great party where you guys would have, like, actual fun. But I understand. You're boring now.
Hailey: So tonight, you guys…
Kirsten: Are going to dinner at The Arches. We do it every year. Home in time to watch Dick Clark and the ball drop…two images that should not be used in the same sentence.
Anna: Well I didn't want you to be alone.
Seth: I'm not alone. I have Captain Oats and Carson Daly.
Ryan: Great, my girlfriend's kissing some guy. I'm stuck here with a lunatic.
Ryan: I sleep here every night. (Pool house) Three of the walls are made of windows.
Seth: Yes, which are now covered with naked dudes. We're trapped like rats.
Ryan: Rats in an enormous pool house. By the way, your aunt's really cool.
Seth: Yeah I know, she's be a bit unpredictable sometimes. My shirt's strangling me.
Ryan: You want a sandwich, a shower, we got all that here.
Seth: Ha ha ha. We're gonna die and I'm the good one.
Seth: I'm claustrophobic.
Ryan: Seth this place is huge. It has a kitchen and a bathroom.
Seth: Sh. Ryan, do not use up all the oxygen.
Seth: Carson Daly and a ball dropping. There is two images that should never be said in the same sentence.
Sandy: Ladies. So I'm gonna go...
Kirsten: Surfing? Fun. Where?
Sandy: At, you know, the spot, you know, by the place.
Kirsten: Four-footers? Yeah, I heard that too.
(Sandy looks around confused, as if he's looking for something)
Sandy: Yeah, I was just gonna ask you.
Kirsten: Kitchen. So tonight?
Sandy: Yeah, what time should I make the reservations?
Sandy and Kirsten: Eight?
Sandy: Perfect. Table?
Sandy: I love you.
Kirsten: Love you too. (Looks at Hailey who has a look of disgust on her face) What?
Hailey: You guys are like....married.
Kisten: Well, that was the idea. When we had a wedding.
Hailey: No, I mean like deeply, deeply married.
Kirsten: Don't call me Kiki! Only dad calls me Kiki, and only because he won't not. (Nods to herself, looking kind of silly)
Kirsten: We would have come and picked you up. At the airport. Or the train station.
Sandy: Or the border.
Sandy: You guys need anything?
Seth: Yes. Ryan needs a tear in the space time continuum.
Marissa: I love you.
Ryan: ... Thank you.
Marissa: You're welcome?
(About Marissa being at a New Year's party without Ryan)
Hailey: So, at the countdown to midnight, when she's looking for someone to kiss and you're here playing video games about pirates...
Hailey: ... and it's like, 10, 9, 8... and she's all alone, when she sees this guy, Oliver... 7, 6, 5... fireworks start, music swells... 4, 3, People are pairing off, who's she gonna kiss?... 2, 1.
Ryan: I love you.
Ryan: I love you.
Marissa: (happy, almost says it back) ... Thank you.
Sandy: I should really knock ... in case there's a threesome going on in my bedroom.
Hailey/Summer: You know what they say. How you bring in the New Year is how you live the rest of it.
Though credited in the opening credits, Chris Carmack (Luke), Tate Donovan (Jimmy) and Melinda Clarke (Julie) do not appear in this episode.
Although Hailey is the adult aunt to the teenage Seth, in reality, Amanda Righetti (who plays Hailey) was 20 when this show aired while Adam Brody (who plays Seth) was 24.

The guy Summer kissed in Oliver's penthouse at midnight on New Year's Eve was named Allan. Allan Heinberg is a co-executive producer and frequent writer for the show.
In this episode Sandy says "I really should knock...in case there's a threesome going on in my bedroom." This is similar to a line in the first episode when Seth is at a party, walks into a bathroom and says "I really should knock... in case there is a threesome going on in the bathroom."
Adam Brody (Seth) mentions the scene where he's claustrophobic, in an online chat archived at the FOX official website. Adam said "There's a scene me and Ben did where we're locked in the poolhouse and I get claustrophobic. And so this girl closes the door on me in the scene, and I actually got hit by the door and it really hurt. So when you see that scene in an upcoming episode, you should know it's for real."
Kirsten: I own a sweater from Talbots.
Talbots is a clothing store devoted to formal wear. Men, women, and kids' clothing are offered at Talbots' stores.
Seth: I think we should join Friendster.
Friendster is an online service site where people come to find old friends, make new ones, etc. It's an online community to simply connect with friends.
The final party scene in the episode is a fairly close imitation of the last scene in "When Harry Met Sally..." (Sally's at a New Year's Eve party with a guy she doesn't like too much, Harry gets there and confesses his love at the last minute.)
Marissa: I don't know. Russell Crowe, he just doesn't do anything for me. I mean people say he's good looking but I don't see it.
Marissa and Ryan are discussing the movie they have just finished watching, Master and Commander: The Far Side of the World starring Russell Crowe.
Russell Crowe, at the time, is one of the biggest movie stars around. Along with numerous awards and nominations, he most notably has been nominated for 3 Academy Awards (Oscars) for Best Actor, winning one of them.
This quote is also an inside joke because most people believe Benjamin McKenzie resembles a "young" Russell Crowe.
