Howard: When they perfect human cloning, I'm gonna order 12 of those.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Howard: I invented a game. Want to play?
Leonard: Sure.
Howard: It's called Emily or Cinnamon. I give you actual quotes I've heard Raj say, and you guess if he was talking to his girlfriend or his dog.

Bernadette: Does your mother call you every day at work to see if you had a healthy lunch?
Howard: My mother calls me every day at work to see if I had a healthy bowel movement.

Leonard: Well, the only way we can play teams at this point is if we cut Raj in half.
Raj: Oh, sure, cut the foreigner in half. There's a billion more where he came from.

Penny: Wait. Wait, Sheldon come back, you forgot something.
Sheldon: What?
Penny: This plasma grenade. Ha! Look, it's raining you!

Leonard: Wow, Penny, you're on fire!
Penny: Yeah, so is Sheldon!
