    • Sheldon: Whoo. I'm all sweaty. Wanny log on to Second Life and go swimming? I just built a virtual pool.

    • Leslie: What sort of experiment would you propose?
      Leonard: There is a generally accepted pattern in this area. I would pick you up, take you to a restaurant, then we would see a movie. Probably a romatic comedy, featuring the talents of Hugh Grant or Sandra Bullock.
      Leslie: Interesting. And would you agree the primary way we would evaluate either the success or failure of the date would be based on the biochemical reaction during the good night kiss?
      Leonard: Heart rate, pheromones, etcetera, yes.
      Leslie: Why don't we stipulate the date goes well and move to the key variable?
      Leonard: You mean kiss you now?

    • Leonard: Anyway,I was thinking more of a biochemical exploration with a neurochemical overlay.
      Leslie: Wait, are you asking me out?
      Leonard: I was going to characterize it as the modfication of our colleague/friendship paradigm with the addition of a date-like component. But we don't need to quibble over terminology.

    • Penny: So, what's new in the world of physics? Leonard: Nothing. Penny: Really, nothing? Leonard: Well, with the exception of string theory, not much has happened since the 1930s, and you can't prove string theory. At best you can say "hey, look, my idea has an internal logical consistency." Penny: Ah. Well, I'm sure things will pick up.

    • Leonard: I'm a perfectly nice guy. There's no reason we couldn't go to the restaurant and have a lovely dinner. Maybe take a walk afterwards, talk about things we have in common. "You love pottery? I love pottery!" You know, there's a pause, we both know what's happening, I lean in, we kiss, it's a little tentative at first but then I realize, she's kissing me back, and she's biting my lower lip, you know, she wants me, this thing is going the distance, we're going to have sex! Oh God! Oh, my God! Sheldon: Is the sex starting now? Leonard: I'm having a panic attack!
