Step one: Character one Inserts coin (or something else . . . )
Step two: Character two tells character one what came out of the machine, (ex. a Bangalter lego, album by Crescendolls, or whatever else you can think of)
Step three: Character two repeats the process
So for example, it would go something like this:
Jack: *inserts coin*
Pyro: Jack gets a box of pencils. *inserts coin*
Victoria: Pyro gets a pair of panties. *inserts coin*
Pyro: Jack gets a box of pencils. *inserts coin*
Victoria: Pyro gets a pair of panties. *inserts coin*
So to start things off, I will stick the first coin in the machine.
