Here's how it goes.
You insert something into the machine. For example, you could insert a dollar, ten dollars or a hundred dollars...Anything works, okay? Then the person below you tells you what you get out of the machine, rather it be a soda, a stripper, a cow, air....anything. Then it starts all over.
Example:
Person #1: *inserts $5*
Person #2: You get a new car.
*inserts an umbrella*
Person #3: You get a sierra mist.
*inserts 25 cents*
And so on and so on..

*Inserts $1*
