Quote from Barney in The Platinum Rule
Ted: Wow, I've got to hand it to Wendy the waitress. That was very mature of her. Barney: She's gonna try to kill me. This is poisoned. [pours drink on floor] Ted: What? You're being ridiculous. Barney: Yours is poisoned too. [pours Ted's drink] She's trying to kill me and everyone close to me. Ted: What are you talking about? Barney: Ted! Look at the facts. I dump her and she says "No hard feelings". She's a psycho! What other explanation is there? Ted: Uh, that you're letting yourself believe she's crazy so you don't have to face the far more likely possibility that she doesn't want to date you either? Barney: Where did Marshall get that hamburger? Ted: I don't know. I guess Wendy the waitress brought it to him. Barney: Noooooooo! [Barney runs, in slow motion, towards Marshall and knocks his hamburger out of his hand] Marshall: Dude. Barney: You're welcome.
