Penny: Yeah, it was fun. Kind of reminded me of my high school. But instead of vampires, we had meth heads. But both came out at night and had messed up teeth.

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

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.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

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.
