Mrs. Wolowitz Howard, what are you doing in there?
Howard: I'm taking a bath.
Mrs. Wolowitz I hope that's all you're doing. We share that tub!

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?

Barry Kripke: Hey, Cooper. I hear you're going to be on the radio with Ira Flatow from Science Friday next week.
Sheldon: Thank you, Kripke, for depriving me of the opportunity to share my news with my friends.
Barry Kripke: My pleasure.
Sheldon: My thanks were not sincere.
Barry Kripke: Ah, but my pleasure is.

Sheldon: Biologically speaking, Howard is perfectly justified in seeking out the optimum mate for the propagation of his genetic line. Howard: Thank you, Sheldon. Sheldon: And whether that propagation is in the interest of humanity is, of course, an entirely different question.

Sheldon: Hello, Kripke. This classic prank comes to you from the malevolent mind of Sheldon Cooper. If you would like to see the look on your stupid face, this video is being instantly uploaded to YouTube. Oh, and a hat tip to Leonard Hofstadter and Raj Koothrappali for their support and encouragement in this enterprise.
