Penny: I can't believe it. All this time I've been doing nothing but sit around and miss that guy. And you know what the worst part is?
Sheldon: That you're having to process your emotional pain without vodka?
Penny: No. Yeah.

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.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

Amy: It would be nice to be with a man who wants to know what's underneath my cardigan. FYI, it's another cardigan.

Sheldon: As rock and roll bad boy Paul Simon once said, "I am a rock. I am an i.....sland".

Raj: Who died and made you the king of moments?
