Mrs. Wolowitz Senior fitness was canceled. It turns out you can forget how to ride a bike. I'm fine, but, oy, did Sam Harpoolian eat gravel.
Howard: That's great, Ma!
Mrs. Wolowitz: What's great about an 80-year-old Armenian man with half his chin scraped off?

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 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.

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.

Sheldon: Why are you crying?
Penny: Because I'm stupid.
Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Penny: Look, can we just forget about this extra stuff and can you just tell me what Leonard does?
Sheldon: Alright. Leonard is attempting to learn why subatomic particles move the way they do.
Penny: Really? That's it? Well, that doesn't sound so complicated.
Sheldon: It's not. That's why Leonard does it.

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.
