Sheldon: Ill tell you where I've been. You boys may have had gelato with Stan Lee and gotten autographed comics, but I saw the inside of his house and got an autographed application for a restraining order.
Howard: Sweet.
Sheldon: Plus, I get to hang out with him again at the hearing. This is going to look great hanging next to my restraining order from Leonard Nimoy.

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.

Sheldon: Good Morning your honor, Dr. Sheldon Cooper appearing in pro se - that is to say representing himself.
Judge: I know what it means, I went to law school.

Sheldon: *After just being jailed, at the biggest guy in the cell who's sitting on a bench* That's my spot.

Sheldon: That's the toilet?
Policeman: Well, it ain't a wishin' well!
Sheldon: Please tell the judge I'm ready to apologize.
