OK, so I actually came up with this idea last week based on a weapon we sell in the shop...
The KING OF IRON CHEF TOURNAMENT! (Yeah, you'll probably have to be a couple of different kinds of nerd to get the joke at this point)
Imagine a reformatting of Iron Chef where, while cooking their dishes, the contestants have a fight to the death, weilding only their cooking utensils...
You wear velcro and jump into a 50 ft pit with spikes on bottom if you can manage to stick to wall you win cash futher down you do it the more the cash. lol
