Penny: When was the last time you got a massage?
Amy: Sheldon walked on my back two weeks ago, but that was just 'cause there was a spider on his pillow and he was trying to get away.
Penny: Leonard stood on me once, too, but he was just trying to see the Rose Parade.

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

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

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

Leonard: I would pull this car over and kick you out, but if Penny dumps me, you're all I got.

Sheldon: Amy is free. She had a harp lesson on Saturday, but it got canceled. Boy, when you take an interest in people, you really uncork a geyser of nonsense.

Bernadette: Things going well with you and Sheldon living together?
Amy: Better than ever. He asks about my day, takes an interest in my life. He's like my boyfriend in college, except he's real, so people can see him.
Bernadette: I've been seeing him for years. I'm still not convinced he's real.
