Bernadette: Oh, and, Penny, she kinda threw up on your stuffed bear.
Penny: Oh, that's okay.
Leonard: Hey. That's an Ewok and it's mine.
Penny: Yeah, which is why it's okay.

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.

Penny: No, I've been reading Bernadette's parenting book. It's like the answer key to the Sheldon test.

Leonard: It's fine, I've been driving him for years. What's one more day?
Sheldon: Oh, and I've got a new car game we can play. It's called "What siren am I?"

Raj: This is great, the two of us hanging out. Why didn't we think of this earlier?
Sheldon: Agreed. I don't need Amy to watch a movie. I can not hold your hand just as easily.
(Sheldon starts the movie)
Sheldon: In the book this is based on, that man's the killer.
