Okay, I don't really want anybody to get, you know, killed or anything, so maybe instead we could pit them against each other on, say, Survivor, or maybe Battle of the Network Stars. In the semi-final rounds I'd like to see:

Steve Irwin vs Jeff Corwin

and

Jim Fowler vs Stan Brock

The winners from these matches would go head-to-head, no-holds-barred to compete for the grand prize trophy -- which will be named after either Marlon Perkins or Jacques Cousteau, depending on who wins in a spitting-for-distance-and-accuracy competition.
