Quote from Barney in The Platinum Rule
Barney: I've decided to seduce Wendy the waitress. Ted: No! Lily: Don't do it! Barney: Request denied! What rule is there that say's I can't seduce the waitress at my favorite bar? Lily: I don't know. I'd expect you to have one already. Robin: Yeah, with some sort of catchy name. Barney: Well, I don't. I don't have one and I never will be because it's a great idea. Come on, guys! She's gullible. I'm bored. We're perfect for each other.
