Penny: That would really piss me off if I didn't have a buzz going on.

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.

Amy: I don't know what made me think tonight would be any different.
Bernadette: Well just the fact you got him up here says a lot. To be honest, I bet Howie $200 that it wasn't going to happen.
Howard: I'm going to the Lego Store to get a big-ass R2D2.
Bernadette: See, it's not just Sheldon, they're all idiots.
Howard: She's right.

Sheldon: What is your problem?
Amy: It's Valentine's day. We're supposed to be having a romantic weekend.
Sheldon: Oh, really? 'cause I remember you saying this trip was going to be something we could both enjoy. Did you mean that or were you just trying to trick me?
Amy: Fine, it's true. I deserve romance and I didn't know how else to make it happen.

Leonard: I'm not sure it's a good idea to take Penny to where wine comes from.
