Okay everyone. I've seen this on quite a few forums. Here's how it works.
One poster inserts something into the vending machine. It can be anything you want.
The next poster says what comes out of the machine and inserts something else into it. Again, it can be anything.
The Pondermatic: *inserts coin into vending machine*
MAXXIMIZER: You get an old boot. *inserts mine into vending machine*
Okay lets go.
*inserts crouton into vending machine*
