While I don't pretend to know the answer to the question, "W.W.J.D.?" I can definitely tell you what I would - or wouldn't - do for a Klondike bar.
Would you stand in a long line to get something for free, even if you weren't quite sure what it was?
Would you be willing to  press a button 5,000 times or bow in front of a big machine in the middle of townsquare?
Apparently, some people would.

Fantastic Delites wanted to find out exactly what lengths people will go to get some free snacks, so they set up a  machine called the Delite-o-matic.

Hilarity ensued.

Play the Delite-o-matic online at http://www.fantasticdelites.com.au and win tasty prizes...  Without the public humiliation.
