Mrs. Wolowitz: That's right. Go back to Babylon, you whore!

Mrs. Wolowitz I'm not going near that fakakta thing. I'll catch a computer virus.
Howard: You can't catch a computer virus.
Mrs. Wolowitz Oh, so now you're an astronaut and a doctor?

Mrs. Wolowitz Howard, it's the phone.
Howard: I know it's the phone, Ma. I can hear the phone.
Mrs. Wolowitz Well who's calling at this ungodly hour?
Howard: I don't know.
Mrs. Wolowitz Well ask them why they're calling at this ungodly hour.
Howard: How can I ask them when I'm talking to you?

Mrs. Wolowitz It's this dress. When I put my front in, my back pops out. When I put my back in, my front pops out. It's like trying to keep two dogs in a bathtub.
Sheldon: What do you want me to do?
Mrs. Wolowitz We're gonna have to work as a team. Get in here, grab a handful and start stuffing.

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!
