Penny: Oh, it's about time. I'm starving.
Leonard: Uh, well, we didn't actually get Chinese food.
Penny: Why not?
Leonard: Don't panic, this is better.
Penny: Oh, no, you didn't trade the food for magic beans, did you?

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: One ring to rule them all.
Rajesh: One ring to find them.
Wolowitz: One ring to bring them all.
Leonard: And in the darkness bind them.
Rajesh: Holy crap are we nerdy!

Sheldon: So, just to clarify, when you say three, do we stand up or do we pee?

Leonard: What was that?
Penny: Sheldon tried to steal the ring so I punched him.
Leonard: That's my girl!
