Penny: Hey, have you ever heard of the Van Nuys Comic-Con?
Leonard: Yeah, it's a dinky little convention where they sell collectibles and get sad D-list celebrities to appear. Why?
Penny: I got asked to sign autographs there.
Leonard: That's awesome! Is this for Serial Ape-ist?
Penny: Well, it could be for the monkey movie. It could be my hemorrhoid commercial. The list does not go on.

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

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?

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

Sheldon: Stuart, wait. I do know what it feels like to be left out.
Bert: I know how it feels, too.
Sheldon: All right, this is about me and him; you're not part of it.

Sheldon: So until Amy's apartment is fixed, she and I are living here together.
Bert: I lived with my old girlfriend. She was a geologist, too.
Amy: Things didn't work out?
Bert: I came home from work one day and she had taken everything. I'm warning you, hide your good rocks.

Stuart: I also love how you never use swear words.
Sheldon: You know, it turns out, you can hurt people just as well without 'em.
