(After Marshall and Lily had sex)
Marshall: That was amazing.
Lily: Yeah. Wanna do it again?
Ted: Please don't.
Katie: Kyle is a really nice guy. He could have cheated on me with my lab partner Gretchen Gwynn, but he didn't, because he said he'd knew I'd find out.
Ted: That's very gallant.
Barney: Watch your step when you get up kids, because I'm about to drop some knowledge.
Marshall: Speaking of waiting, I signed an abstinence pledge in high school. It's totally cool to wait. And stay away from drugs, other than pot. *Winks*
Robin: Usually, by now I find out the guy has some weird personality thing that makes me want to take the next exit.
Lily: Yeah, I've been there. I once dated a guy who could only go to the bathroom when classical music was playing ... Okay, it was Marshall.
Ted: Come on, you were only 16 when you had sex, I was 17.
Marshall: You were 18.
Ted: Barney was probably 12.
Barney: Good one Ted. I was six ... ff ... four ... How old were you again?
Barney: Dude, me too!
Robin's Sister: You were only 16 when you lost yours.
Robin: How do you know that?
Robin's Sister: Because you left your diary in your old room slash my new room.
Barney: I'll pay you $10 000 for that diary!
Robin: I'm her older sister. I'm suppose to teach her how to make good and responsible decisions.
Lily: It's 2 o'clock and you've already had three scotch and sodas.
(Robin's sister is planning to lose her virginity.)
Robin: This can't happen, you guys have to help me talk her out of it!
Marshall: A speech to talk a girl out of having sex..
Ted: Yeah, I don't have any of those.
Barney: Discouraging premarital sex is against my religion.
Barney: Freeways have exits, so do relationships. The first exit, my personal favorite is 6 hours in, you meet, you talk, you have sex and you exit when she's in the shower.
Robin: So every girl you have sex with feels the immediate need to shower? Actually yeah, I get that.
