Sheldon: You're holding a Japanese puzzle box, which takes ten precise moves to open. First, locate the panel with the diamond pattern and slide the centre portion one millimetre to the left. Then, on the opposite end of the box, slide the entire panel down two millimetres. You'll hear a slight click.
Penny: Hang on. Sheldon, do you have any emotional attachment to this box?
Sheldon: No, it's a novelty I ordered off the Internet. Now, did you hear the click?
Penny: Not yet. (Puts the box on the ground and stomps on it)There it is.

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

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.

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

Sheldon: She calls me moon-pie because I'm nummy-nummy and she could just eat me up.

Leonard: Well, it looks like you're caught between a rock and a crazy place.
Sheldon: I hate when that happens.

Sheldon: No one calls me Moon Pie but Meemaw.
