Mrs. Wolowitz Has she tried on the vest yet?
Howard: I just gave it to her.
Mrs. Wolowitz I hope it fits. She's a tricky figure. She's short and stacked, like me.

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.

Amy: Jewelry? Seriously? Sheldon, you are the most shallow, self-centered person I have ever met! Do you really think another transparently manipulative - Oh, it's a tiara! Put it on me, put it on me, put it on me, put it on me.

Penny: You look beautiful.
Amy: Of course I do, I'm a princess and this is my tiara!

Sheldon: Hard as this may be to believe, it's possible that I'm not boyfriend material.
Leonard: Glad I was sitting down for that.
