Wil Wheaton: Listen, Sheldon, I'm really happy to do this for you, but not if she's gonna be a huge pain in the ass the whole time.
Amy: You gonna let him speak to me like that?
Sheldon: Well, you're my girlfriend and I don't want you to be upset. Then again, Wil Wheaton's my friend and I don't want him to be upset. Hmm, this is a sticky wicket. (To Wil) What do you think?

Raj: I don't like bugs, okay. They freak me out.

Sheldon: Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and as it always has, rock crushes scissors.

Sheldon: Why are you crying?
Penny: Because I'm stupid.
Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Mrs. Wolowitz: Howard, help, my hand's stuck in the garbage disposal.
Howard: Let go of whatever piece of food you're holding.

Amy: And action.
Wil Wheaton: And cut! You realize I'm doing this for free, right?
Amy: Yes, and so far we're still not getting our money's worth.

Wil Wheaton: Problem, first time director?
