I know my dad is gonna love this one...

"I've invented a new game-- X-treme Backgammon.

X-treme Backgammon is when halfway through someone explaining the rules of Backgammon to you, you bite them and then eat the dice.

The X-treme part really comes later, when you're passing three dice out your urethra. The bad news is that it irreparably damages your ability to pee. The good news is that I rolled an eleven in the toilet."
