Howard: So, what do you think? Do you like her? She's great, huh?
Mrs. Wolowitz: She's a lovely girl. Cute as a button.
Howard: That's good to hear, 'cause I've got some news.
Mrs. Wolowitz: I hope it's good news, because I've got nothing but disappointment in here!

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 Should I ask Leonard to bring over your homework?
Howard: I don't have homework. I'm a grown man with a master's degree in engineering.
Mrs. Wolowitz Excuse me, Mr. Fancy Pants. Want me to get you a popsicle?

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: Oh, what fresh hell is this?
Biosuit Nurse: Wait, you can't leave here, you've been exposed.
Sheldon: (Covering his face with his shirt) No, I haven't. It's all good.

Howard: Hell hound.
Raj: Who let the satanic dogs out?

Raj: Sheldon, that's my water.
Sheldon: Oh, dear Lord!
Leonard: That's not your water.
Raj: I know.
