Sheldon: All right, pick a card.
Howard: Okay.
Sheldon: Bippity-boppity-boo.
Howard: What's with the wand and the beep?
Sheldon: The wand is called showmanship, and the beep is none of your business. Oh, excuse me, I'm getting a text message completely unrelated to this magic trick. Oh, look, my dry cleaning's ready. And your card was the five of spades. Ta-da.
Raj: These cards have bar-codes on them. The wand is a reader. It's transmitting to your phone.
Sheldon: I said, ta-da. Show's over.

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.

Penny: Oh, big deal. Not knowing is part of the fun.
Sheldon: "Not knowing is part of the fun." Was that the motto of your community college?

Rajesh: Why so glum, chum?
Sheldon: Apparently you can't hack into a government supercomputer and then try to buy uranium without the Department of Homeland Security tattling to your mother.

Sheldon: So, you're saying this is a regulation deck?
Howard: I'm saying believe in magic, you muggle.
