Lily [about Canadian sex acts]: How do you know all these?
Barney: Canadiansexacts.org. It's bookmarked on the top right.
Marshal: Dot org?
Barney: Yeah, it's not for profit. They really just want to get the information out there

Marshall: Ted, Karen's a douche.
Ted: Wow, thanks for sugar-coating it.
Marshall: "Douche" is sugar-coating it

Robin: Thanks for coming by. I monkeyed around with the thermostat for about an hour before I realized it was the intercom.
Marshall: Yeah, I heard you swearing downstairs

Robin: I still say this is stupid. What happened to, "As we mature, the relationship matures with us?"
Marshall: That's just something Lily read in Psychology Today. Alright, she read it in Cosmo. Alright, I read it in Cosmo. Alright, it was CosmoGirl!

Lily [on the phone]: Hey, baby. It's lunchtime, and I love you.
Marshall [on phone in front of co-workers]: I reciprocate in principle, although with the caveat that there seems to be a bit of a surplus here on my end.
Lily: No, I love you more.
Marshall: Do we need to get in a room together and bang this thing out? (pause) Those sound like agreeable terms, although I may need to adjust my briefs

Ted: So, last night Robin left the pizza box out on the floor, so we had sex three times.
Marshall: Sure.
Ted: And then this morning, before I left for work, we kissed.
Marshall: Oh, that's weird. That is weird!

Ted: There aren't any black people in Minnesota?
Marshall: Not if Prince is on tour

Marshall: You know what, Doug, I will gladly pay. And you know why? Cause that's what grown-ups do! They pay for their drinks and they don't get into fights. You know what I was doing while you guys were out there being immature? I tell you what I was doing...
Barney: ...your nails?!
Marshall: Haha, No, I was doing...
Ted: ...a relationship-quiz in this month's Cosmo?!
Marshall: No, I was doing...
Barney: Your best not to cry when Big came back for Carrie at the end of the Sex and the City movie?!

Barney: I know. We are Swedish. We are so cool with our baguettes and our Eiffel Tower.
Marshall: Dude, Sweden is not France, you know that, right?
Barney: Oh, it's France!

Marshall [looking inside Barney's "Not a Fathers Day" card]: It appears to be some sort of Asian hooker.
Barney: Yes, because on Not a Fathers Day, you get a Thai you'd actually wear! Wordplay five!

Stella hated Star Wars! She lied to you. Search your feelings, Ted. You know it to be true

Marshall: There's no meat.
Lily: There's no alcohol.
Marshall: It gets worse—I am 90% sure that guy you were talking with used to be lead singer of the Spin Doctors
