He could be lured out of retirement for enough money. He has previously said $1 million would do it.
Yeah but nobody is going to GIVE him a million dollars to compete, but if he was smart and had a little of Bob Chick's hustle in him, he could parlay winning a contest like that into a shit-ton of endorsement deals.
He could become a huge figure for the over 40 crowd....and we have bank

Imagine K-lo doing some infomercials pushing XYZ supps, with some footage from the contest mixed in, with his age right there on the screen....people would buy "cutting edge GH releasers" and "Pharmaceutical grade Test boosters" from him in droves. He needs to stop making backyard videos for his "peeps" and go after the fat bastards with money. IMO this contest could be a springboard right into that
