Okay, what's the big deal? Look, if it helps me make a sale with a physician, I don't think it hurts to flirt a little. I mean, laugh at their joke, touch their arm, maybe crank up the AC in the car beforehand, you know, to wake up the girls.

You know, maybe if fashion magazines had female scientists in them, I would've become a theoretical physicist. Stop smirking at each other.

Penny: The real question is: What is he doing in your apartment?
Leonard: Oh, he was upset. So Sheldon invited him in for a hot beverage.

Penny: You locked them in your basement?!
Dr. Lorvis: Well, they're, they're not locked in. The door just sticks.

Dr. Lorvis: They'd need the key.

Penny: Prom is silly anyways.
Bernadette: Easy for you to say; you probably went with the captain of the football team.
Penny: No. I just made out with him a little while his date was puking.

Penny: That, believe it or not, is my prom dress.
Bernadette: Wow, you still have it? I just assumed it was balled up in the corner of a barn somewhere.
Penny: What kind of teenager did you think I was?
Bernadette: Slutty.
Amy: Easy.
Penny: The word is "popular."

Penny: Here's a question-- as an alien pretending to be human, are you planning to engage in any post-prom mating rituals with Amy?
Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
Penny: You're kidding.
Sheldon: I may be an alien, but I have urges.If Amy wants to copulate by firing her eggs into space, well, then, I will happily catch them with the reproductive sac on my upper flermin. I'm not the best at reading facial cues, but I can see that you're a little turned on.

Sheldon: But you don't have a life-threatening condition. Why would you take the risk of surgery?
Leonard: Sheldon, it's a routine procedure.

a pain in the ass.
Sheldon: The reason I was being a pain in the B is because I was worried about him, and no one else was.
Penny: Really? You won't even say "A"?
Sheldon: You bet your sweet B I won't.

Dan: Bernadette. Cute, sweet...vicious little Bernadette.
Penny: Come on. She's not that bad.
Dan: Oh, yeah? At the company picnic she yelled at me and my grandson for losing the three-legged race. I mean, he still calls her "that mean kid with the big boobies."

Bernadette: What's his problem?
Penny: Oh. I don't know. Maybe he didn't like the fact that you called his grandson a wuss.
Bernadette: Well, I didn't think you were supposed to say "sissy" anymore.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
