Raj: What happened?
Sheldon: Obviously another carnal fiasco with the 'Shiksee' goddess.
Howard: Shiksa. Shik-Sa.
Sheldon: Forgive me. Yiddish was not spoken in East Texas. And if it was, it wasn't spoken for long.

Leonard: Why would you buy peppermint schnapps?
Penny: Because I like peppermint, and it's fun to say schnapps!

Wolowitz: Sex is never the way I dreamed it was going to be.
Raj: Because in your dreams, you're a horse from the waist down.

Howard, you know me to be a very smart man. Don't you think that if I were wrong, I'd know it?

Sheldon

you're missing the point, a Shiksa goddess is not an actual goddess, we prey on them, not to them

Wolowitz

Leonard: Will you take that stupid red hat off?
Wolowitz: No, I want to blend in
Raj: To what? Toy story?

Leonard: I don't want to go to Texas
Wolowitz: Alright and I do? My people already crossed the desert once. We're done

Wolowitz [about his mustache]: I call it the Clooney
Raj: I call it the Mario and Luigi, but whatever

Penny: You know, I do understand what you're going through.
Sheldon: Really? Did you just have the Nobel Prize in Waitressing stolen from you?

Hello, Penny. I realize that you're currently at the mercy of your primitive biological urges, but as you have an entire lifetime of poor decisions ahead of you, may I interrupt this one

Sheldon

Wolowitz: Sheldon. You remember the first few weeks; we were looking for magnetic monopoles and not finding anything, and you were acting like an obnoxious, giant dictator?
Raj: I thought we were going to be gentle with him.
Wolowitz: That's why I added the "tator"

Wolowitz [after seeing Penny jump Leonard]: Damnit, I should have gone over and said we were back
Raj: Yeah, it was "first come, first serve."

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
