Priya: Nice of you to come for Howard.
Penny: Well, he's my friend. It's what you do. (Laughs)
Priya: I'm sorry, did I miss something?
Penny: It's just so weird. Howard Wolowitz is my friend. You know, once he tried to stick his tongue down my throat and I broke his nose.
Priya: That's a little easier to believe than he's your friend.
Penny: Yeah, tell me about it.

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: Oh, what fresh hell is this?
Biosuit Nurse: Wait, you can't leave here, you've been exposed.
Sheldon: (Covering his face with his shirt) No, I haven't. It's all good.

Howard: Hell hound.
Raj: Who let the satanic dogs out?

Raj: Sheldon, that's my water.
Sheldon: Oh, dear Lord!
Leonard: That's not your water.
Raj: I know.
