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.

Bernadette: Besides, Penny and I are having a girl's night tonight.
Amy: Girls night, what does that entail?
Bernadette: Oh you know, girls get together hang out share girl talk.
Amy: I'm a girl.
Bernadette: Oh well maybe you could join us. I'll ask Penny.
Amy: No need, Penny and I are very close.
Leonard: You are?
Amy: Yes, In fact our mensies are synchronized.

Penny: You locked them in your basement?
Dr. Lorvis: Well, they're not locked in. The door just sticks.
Penny: Okay, so how do they unstick it?
Dr. Lorvis: They'd need the key.

Penny: Okay, you can't just go chasing after every girl who's nice to you.
Dr. Lorvis: Well, that's not what Sheldon says, and he seems to know his way around the ladies.

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.

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.

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.
