Quote from David in The One with the Monkey
David: But you can't actually test this theory. Today's particle accelerators aren't powerful enough to simulate these conditions. Phoebe: Okay, I have a question then. David: Yeah? Phoebe: Were you planning on kissing me ever? David: That's definitely a valid question, and the answer would be yes. Yes, I was. But I wanted it to be this phenomenal kiss at a phenomenal moment because it's you. Phoebe: Sure. David: Right. But, see, the longer I waited, the more phenomenal the kiss had to be. And now, it's just gotta be one of those things where l just, like, sweep everything off the table and throw you down on it. And I'm not really a sweeping sort of fella. Phoebe: David, I think you are a sweeping sort of fella. I mean, you're a sweeper trapped inside a physicist's body.
