TBBT Quotes

Penny: Here's a question-- as an alien pretending to be human, are you planning to engage in any post-prom mating rituals with Amy?
Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
Penny: You're kidding.
Sheldon: I may be an alien, but I have urges.If Amy wants to copulate by firing her eggs into space, well, then, I will happily catch them with the reproductive sac on my upper flermin. I'm not the best at reading facial cues, but I can see that you're a little turned on.

Sheldon: Ugh! English pudding. Y-You get yourself all excited for pudding, and here comes a cake with raisins in it. I'm not going.
Amy: You're going.
Sheldon: Why do you hate me?
Amy: I don't hate you. I love you.
Sheldon: Well, you call it love, but it has a lot of raisins in it.
