Marshall: Relationships are like that. I mean, look, when you first met Don, you hated him. You thought, "This guy's a duck." But one of these days, you're gonna realize, "This is actually something that I love. He's a rabbit."
Ted: Whoa. I think you got it backwards there, buddy. The duck is the thing you love. The rabbit is the thing you hate.
Marshall: What?
Robin: Yeah, I gotta agree. Ducks up, rabbits down.
Lily: Definitely, ducks are better than rabbits.
Marshall: Are you guys... Ducks are... Ducks are... Rabbits are adorable. Ducks are, well... Have you ever been in a fight with a duck? I mean, ducks are jerks.
Future Ted: [v.o.] This led to one of the most intense arguments our group has ever had. [fast-forward]
Ted: Duck is delicious. Rabbit is all gamey!
Marshall: We're not talking about flavor, Ted!
Ted: Flavor counts! [fast-forward]
Marshall: Who carries around a duck's foot for good luck? Anyone? [fast-forward]
Robin: You wrap yourself in a comforter stuffed with rabbit hair. I'll wrap myself in one stuffed with duck feathers. Who's cozier? No, no, no, no, no, no, no. But who's cozier? [fast-forward]
Ted: Hold on! I have to get another book!
Ranjit: [speaking forcefully in a foreign language; fast forward]
Ted: Then why don't we take a rabbit, a duck, stick 'em in a cardboard box, and let them fight it out?
Marshall: Because it's illegal, Ted!
Ted: Only if we bet on it, Marshall! [fast-forward]
Marshall: Fine! I concede! You win.
Robin: Say it.
Ted: You have to say it.
Marshall: Ducks are good. Rabbits are bad.
