Sheldon Cooper:
[exiting change room] I'm going to need a larger shirt! This one's a little tight under the arms.

Jimmy:
Okay. [takes shirt]

Leonard Hofstadter:
Do you think maybe it's tight because you're wearing long underwear?

Sheldon Cooper:
Yes, of course that's why it's tight.

Leonard Hofstadter:
All right, let me rephrase the question. Why are you wearing long underwear?

Sheldon Cooper:
You're kidding! Shouldn't the question be "Why *aren't* you?"

Leonard Hofstadter:
No, it should be "Why are you?"

Sheldon Cooper:
Leonard, these rental tuxedos have been worn by *hundreds* of sweaty strangers. Yeah, I don't like my own sweat touching my skin; how do you think I feel about theirs?

Jimmy:
Why don't you slip this on?

Sheldon Cooper:
Said the hangman, offering a noose. [returns to change room]

Raj Koothrappali:
Well, that wasn't as entertaining as when he rents bowling shoes, but it was right up there.
