Raj: I've said this before and I'll say it again: Aquaman sucks!

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Zack: You know, I saw this great thing on the Discovery Channel. Turns out if you kill a starfish it'll just come back to life.
Sheldon: Was the starfish wearing boxer shorts? Because you might have been watching Nickelodeon.

Sheldon: I'm not Sheldon. I'm the Flash. And now I'm going to the Grand Canyon to scream in frustration. *takes two quick steps* I'm back.

Zack: You're inferring I'm stupid.
Sheldon: That's not correct. We implied you're stupid, you then inferred it.
