Leonard: I did not force you to go to that.
Penny: You left the house in a fez and a bow tie. I went so you wouldn't get beat up.
Leonard: I wasn't going to get beat up.
Penny: You were but somehow I held myself back.

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.

Bernadette: Are you okay?
Raj: No, I'm not okay. I feel like I'm going to jump out of my skin.
Bernadette: I told you not to wax down there. It's itchy when it grows back.

Penny: Do I really force you to do things you don't want to?
Amy: Yeah, but it's okay.
Penny: How is it okay?
Amy: I promised myself if I ever got friends I'd do whatever they said. Really, I'm lucky you found me before a cult did.

Penny: Ooh, we could go horseback riding.
Amy: I actually can't. My hips don't open wider than 22 degrees. I rode a very thin pony once. On the first bump I just popped right off.
