Penny: Seriously, none of you liked it?
Bernadette: I thought it was brave. Does that count as liking it?
Penny: You know, how come nobody's talking about Howard's dopey haircut?
Bernadette: I think he looks cute.
Howard: And I think you're cute.
Raj: I think you're both cute.
Penny: I think I hate all of you nerds.

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.

Howard: What do you think?
Barry Kripke: That ... is ... hilarious! Give me the remote control. I want to drive him into the girls' restroom.
Howard: All right, we're done. It's offensive.

Amy: Bert is studying the way microbes in rocks can survive in extreme environmental conditions.
Leonard: They say it could be a potential indicator of life on other planets.
Penny: You know what, I've met Bert. Isn't he an indicator of life on other planets?
Sheldon: You used to make those jokes about me. Now everything's Bert, Bert, Bert.

Raj: Well, I'm glad to see you moving forward.
Sheldon: Bert did quality research. And he deserves whatever accolades he receives.
Howard: What is going on? (To Leonard) Did you upgrade his software last night?
Leonard: I think he might be learning on his own.
Raj: Then the robot uprising has begun.
