Leonard: What are you doing here?
Howard: Well, usually, on Sundays, I go with Raj to scam on hippie chicks at the farmers market, but he's still working with Sheldon, so I thought I'd come over here and make you guys scrambled eggs and salami. It's the perfect meal for apres l'amour.
Penny: Oh, kill me.
Howard: By the way, I couldn't help overhearing your big finish. Bravo, Leonard.
Penny: See, if you had killed me when I said kill me, I wouldn't have had to hear that.

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.

Leonard: I've always been a little confused about this. Why don't Hindus eat beef?
Raj: We believe cows are gods.
Sheldon: Not technically. In Hinduism, cattle are thought to be like God.
Raj: Do not tell me about my own culture, Sheldon! In the mood I'm in, I'll take you out, I swear to cow!

Sheldon: There's a fine line between wrong and visionary. Unfortunately, you have to be a visionary to see it.

Rajesh: Okay, please don't take this the wrong way, but I'd rather swim buck naked across the Ganges with a paper cut on my nipple and die a slow agonizing death from a viral infection, than work with you.
