"The Meat Locker: The World's Most Well-Endowed Man" (I took it upon myself to title the show)
Great title, Yng! I'm not sure I'd bother with trying to get celebrities, though... Maybe a bunch of "unknowns" who happen to have made themselves known to us on this site... And "The World's Most" would probably be too ambitious. I'm afraid I'd also have to insist that they be in good shape.
That said though, I love the visuals. Five guys, clad only in Speedos or nothing at all, lounging around having insipid conversations, doing silly contests... but no one would be sent away, just keep them all there for a month or two. Can we sell the idea to one of the networks?
Better yet, actually have them work on real world problems. Have them competing to be the most helpful, the most productive, the one with the best leadership skills, and the one best able to follow instructions when it's not his turn to be the leader. Challenge them to design a car that doesn't use gasoline or a house that functions off the grid. Reward the one who produces the least amount of garbage or keeps himself the cleanest while spending the least amount of time in the shower. Have them develop an quick and easy alternative to fast food that is healthy and fresh. See who can get the most produce out of a garden after a month or two "in the house" or "on the island."
Really, I haven't watched all that many "reality shows," but it seems like they could be stretching these people a little more productively than they do!
