Man's Voice: You want me to hide in the closet or go out the back?
Mrs. Wolowitz: Shh, you need to whisper.
Howard: Ma, who is in there?
Mrs. Wolowitz: Uh, nobody. The TV is on.
Man's Voice: I only got one sock. Where's my other sock?
Howard: Who is that?
Mrs. Wolowitz: I told you, it's the TV. Jay Leno lost a sock, it's hilarious.

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.

Howard: Wow, so you guys are like buds now?
Raj: Oh, yeah, we hang out all the time.
Stuart: Plus, he doesn't have a girlfriend, I don't have a girlfriend.
Raj: It's like we both had these holes in our lives, but now we fill each other's holes.
Stuart: That sounds a little funny to an American ear.
Raj: Which part?
Stuart: Just all of it.

Amy: We could go to the cadaver lab at UCLA and play real-life Operation.
Leonard: Uh-uh.
Sheldon: No.
Penny: I don't think so.
Amy: Are you sure? I mean, the nose doesn't light up, but if the corpse is fresh enough, sometimes you can get the leg to jerk.

Penny: You're unbelievable.
Sheldon: I know.
