Mrs. Wolowitz What's going on? Are you boys roughhousing?
Howard: We're just talking, ma.
Mrs. Wolowitz If you don't settle down right now, I'm not going to let you have any more sleepovers.

Howard: Hey, ma, can I have lamb stew for dinner?
Mrs. Wolowitz: Lamb stew? I'd have to go to the supermarket.
Howard: Please? I got a real hankering.
Mrs. Wolowitz: Oh, I can't say no to my little tushie face. I'll be back soon.

Mrs. Wolowitz Howard, there's a blonde girl, Patsy, here to see you.
Howard: Who?
Mrs. Wolowitz Okay, now she's saying it's Penny.

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?

Sheldon: I wouldn't tell you the secret. Sssh!
Leonard: What secret? Tell me the secret.
Sheldon: Mom smokes in the car. Jesus is okay with it, but we can't tell dad.
Leonard: Not that secret, the other secret.
Sheldon: I'm Batman! Ssssh!

Penny: Sheldon, could I ask you a question?
Sheldon: I would prefer that you not, but I wouldn't go so far as to forbid it.

Leonard: How could you just sit there and let them spy on me?
Sheldon: They were very smart. They used my complete lack of interest in what you are doing.
