Leonard: This conference is kind of a big thing. The keynote address is being delivered by George Smoot.
Penny: Oh my God, the George Smoot?
Leonard: You've heard of him?
Penny: Of course I haven't.

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: She calls me moon-pie because I'm nummy-nummy and she could just eat me up.

Leonard: Well, it looks like you're caught between a rock and a crazy place.
Sheldon: I hate when that happens.

Sheldon: No one calls me Moon Pie but Meemaw.
