Penny: Come on, just open it.
Raj: You know, on Game of Thrones, Balon Greyjoy received his son's genitals in a box.
Penny: Well, never hurts to have a spare.

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?

Leonard: Hang on. Maybe there should be a "no insult" clause about me, too.
Sheldon: Do you still like cilantro?
Leonard: Yeah.
Sheldon: You're tying my hands here.

Howard: See, he's not wearing a tie.
Leonard: Well, he's a patent attorney. Maybe his tie is pending.

Leonard: Hold on, hold on. So the three of us do all the work and only end up with 25%? Patent Attorney: Dr. Hofstadter, this university has been paying your salaries for over ten years. Did you think we do that out of the goodness of our hearts?
Leonard: Well, until you just said that mean thing, kinda.
