Leonard: I think you'll like the next one better. All the cheerleaders are suffering from an evil curse.
Penny: Oh. Well, that's like my high school, too. But instead of a curse, it was crabs.

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: Well, that stinks. No wonder you got cancelled. Bye.

Amy: Missed one. Now your wish can't come true.
Sheldon: Lucky for you because I wished you were dead.

Sheldon: You don't know what it's like to feel completely frustrated. To have a desire build up within you and be denied any opportunity for release.
Amy: Yeah, sounds like a drag.
