Bernadette: Howie, slow down.
Howard: I can't. I'm not allowed to eat for 12 hours before my surgery, and I only got two more minutes.
Leonard: What surgery are you having?
Raj: I'm stress eating. My best friend's getting a vasectomy tomorrow.
Penny: And you're sad you won't be able to bear his child?

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

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

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.
