I sort of stole this idea from Inoka1 from the DragonCave forum, so credit goes to her/him!

Their thread: The original Vending Machine game!
Ok, here's how the game goes:
You insert something, and the person below you gets to pick what you get! Then they insert something and so on!
Example:
Poster A: *inserts cookie*
Poster B: You get a notebook! *Inserts nickel*
And it goes on and on! Remember, you don't have to insert money and it certainly can be random.
I'll start
