The Big Bang Theory, Season 3

Leonard:
[About everyone's Valentines Day plans] Okay, to sum up, one giant marble horse [Howard], one... asinine comment [Sheldon], one lonely man and his chicken [Raj] and that leaves... oh, that's right! My plans! [no one responds] Isn't anyone gonna ask?

Raj:
Fine, tell us you're gonna have sex with Penny.

Leonard:
No, that's not was I was going to say.

Raj:
It's okay, I don't mind hearing about your sex life, it's his [Howard's] that bugs me.

Leonard:
That's not what I was going to say. Guess who the university is sending to see the Hadron Collider in Switzerland?

Sheldon:
Professor Norton, although God knows why. He hasn't published anything in years since he won that Nobel prize.

Leonard:
Actually, he can't go. He threw his back out rock climbing.

Howard:
I heard he threw his back out climbing his new girlfriend.

Raj:
The big-boobed weather girl from Channel 2?

Howard:
That's the one.

Leonard:
Anyway, since he can't go, the university is asking me to fill in for him!

Sheldon:
In Switzerland or on the big-boobed weather girl?
