Amy: I don't understand. Is this a way to break in new shoes?
Penny: No. Once these puppies touch the ground they're mine, and I'll have to wear them walking up and down Hollywood Boulevard in order to pay them off. Pretty, pretty, pretty.

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

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

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

Raj: She didn't even get to see my penis.

Sheldon: There's no need to interact with me. I'm just here to observe.

Penny: I'm sorry, shoes, but you have to go back.
Shoebox (Penny): But, Penny, we love you.
Penny: I love you, too, but you cost more than my rent.
Shoebox (Penny): But Penny, you look so good in us.
Penny: (To Amy) Damn it, the shoes are right!
