Sheldon: Of course not. And, technically, magic beans would be food, although eating them would be quite a waste, since you could plant them and overnight have a giant beanstalk, which would provide enough roughage for a small city.
Penny: Yeah, sometimes I dont listen, sometimes I just watch your jaw go up and down.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

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

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!

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

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