 * Leonard: I mean, 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?
