The Big Bang Theory Season 8 Quotes

Amy: Wait, She-Hulk's a lawyer?
Howard: Yeah, she works at a law firm in New York.
Sheldon: Yes, but she's the only monster at the firm. Between you, me and the wall,I think she's an affirmative action hire.

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.
