Penny: Uh, no. No, baby. I'm not your mama. Your mama's the nice lady we're gonna go see right now so I can rub this in her face. Do you hear that, suckers? She called me Mama!

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Sheldon: Until next week, this is Professor Proton saying, 01000010 01111001 01100101. That's "Bye" in ASCII binary, or good-binary.

Amy: Well, what was wrong with it? You know, did you find it borderline psychotic? I mean, I liked that about it, but you guys discuss.

Sheldon: Some things shouldn't be rebooted. Some things were perfect the way they were. Like the walled city of York, it was a delight. But New York? Blech.
