I don't know. I'm second guessing my first answer.
Jake looks like a scrapper, and he looks like he could handle business if he needed to.
It would definitly come down to Jake or Tony.
Tony Little would have to burn out faster than any other, though Richard Simmons would be crying in the corner like a little girl as soon as it started, so there's a chance he might be safe for a few rounds.
As soon as he gets on his high-horse and tries being tough, he'd get flattened by any one of them.
Maybe John and Richard will be consoling each other while Tony and Jake go at it.
I predict a marriage out of John and Richard, of course Richard would be the bride (bitch).
