Two stages:  Stage one - Fill a container half full of them and food. Put cameras in there. Watch the ensuing fights during their transport to Africa (seems like the only place you'd be allowed to have a proper coliseum.) Stage two - The survivors get out of the container and get a 20oz Mt Dew and a bag of Doritos (our sponsors) to "fuel up". This is obviously only a snack for them. They're then released into the arena where a pizza is on a platform ~5ft off the ground. Once someone has beaten everyone else down, you can then enjoy the show as they struggle to make it onto a 5ft platform.
