Leonard: Hey, look who's out after dark, like a big boy.
Sheldon: I was out raising heck with Mr. Wil Wheaton. Four hours more and we would have closed down the HomeTown Buffet.
Leonard: I thought you had plans with Amy.
Sheldon: Yeah, I did, but then Wil called Amy a pain in the A-S-S. She got huffy and left, then Wil and I headed out to dinner. That place really did remind me of my hometown. Because there we also have a HomeTown Buffet.

Raj: I don't like bugs, okay. They freak me out.
Sheldon: Interesting. You're afraid of insects and women. Ladybugs must render you catatonic.

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.
Mrs. Wolowitz: Are you kidding? It's a perfectly good chicken leg.

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?
