The Big Bang Theory, Season 3

Sheldon:
Waterfalls!

Raj:
What?

Sheldon:
Waterfalls, crashing waves, babbling brooks.

Howard:
What are you doing?

Sheldon:
Subliminal messaging. I'm going to make you want to pee. Dripping faucets, leaky gutter, peeing.

Raj:
It's not working, dude.

Sheldon:
Oh, it's working, alright. I have to pee.

Raj:
Then let go of the ring and go.

Howard:
Well, actually I wouldn't mind going either.

Raj:
Well, on the count of three. 1, 2...

Sheldon:
Wait, just to be clear. When we get to three, do we stand up? Or do we pee?

Howard:
We stand up.

Sheldon:
Excellent choice.

Raj:
3.

Howard:
Something tells me this was a bad day to wear suede shoes.
