The Big Bang Theory, Season 2

Sheldon:
Oh, look! Saturn 3 is on.

Raj:
I don't want to watch Saturn 3. Deep Space 9 is better.

Sheldon:
How is Deep Space 9 better than Saturn 3?

Raj:
Simple subtraction will tell you it's six better.

Leonard:
Compromise. Watch Babylon 5.

Sheldon:
In what sense is that a compromise?

Leonard:
Well, 5 is partway between 3 and... never mind.

Raj:
I'll tell you what. How about we go 'Rock-Paper-Scissors'?

Sheldon:
Ooh, I don't think so. Anecdotal evidence suggests that in the game of 'Rock-Paper-Scissors', players familiar with each other will tie 75-80% of the time due to the limited number of outcomes. I suggest 'Rock-Paper-Scissors-Lizard-Spock'.

Raj:
What?

Sheldon:
It's very simple. Look -- Scissors cuts Paper, Paper covers Rock. Rock crushes Lizard, Lizard poisons Spock. Spock smashes Scissors, Scissors decapitates Lizard. Lizard eats Paper, Paper disproves Spock, Spock vaporizes rock, and as it always has, Rock crushes Scissors.

Raj:
Okay. I think I got it.

Sheldon & Raj:
Rock-Paper-Scissors-Lizard-Spock! [both play Spock and groan in frustration]
