Raj: So you have tattoos?
Emily: Yeah.
Raj: I don't. I have a hole in my belly button that may or may not have been a piercing.
Emily: That's cool.
Raj: It's a piercing.

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.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

Bernadette: I'm glad I got that mocha. And you know what else I'm glad about? I bought you a brownie and I ate it in the car!

Penny: I finally realize I don't need to be famous or have some big career to be happy.
Leonard: Well what do you need?
Penny: You, you stupid Poptart.
