Barney: I'm thinking I'm gonna hop on the Long Thighland Expressway, stop off for a nibble in Breastport, and then, with any luck, I'll be pulling into the Pork Authority by midnight.
Lily: Wait. You're finally going to Bootytown?
Barney: Look, we just don't want to rush anything, okay? So we decided to wait until she decides to let me have sex with her. And that's gonna be tonight!
Ted: How do you know for sure?
Barney: Ah, something she said earlier.

Nora: Guess what, my sweet boy, I've got a special treat for you tonight.
[present:]
Lily: Oh, yeah, you're going to Bootytown.
