Sheldon: Are you Todd Zarnecki?
Todd Zarnecki: Yeah. Who are you?
Sheldon: I am Sheldor of Azeroth. I want my things back.
Todd Zarnecki: I don't think so. Let me see that.
Sheldon: Careful. That's a collectible.
Todd Zarnecki: I know. I've always wanted one. (Closes door, taking Sheldon's bat'leth)
Sheldon: Well, he's even more cunning than we thought.

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: Give my friend his stuff back.
Tod Zarnecki: I don't know what you're talking about.
Penny: Well then good news. Today's the day a girl's finally going to touch you in your little special place. *Kicks him in the groin*

Raj: Come on, dude, bros before ... my sister.

Sheldon: I've never said these words before, but good job, Howard.
