I don't know why he doesn't try to get into the WWE. They could market him as the world's strongest man (like they did with Mark Henry)
Mark Henry was legit, having won the first Arnold Pro Strongman contest in 2002. I believe he pressed a 365-lb Apollon's Wheel. He also pressed the "Inch Dumbbell", which was something like 240-lb at the time, but did this with solely the use of one hand. The thickness of the handle also made it a nightmare to press. The Circus Dumbbell record today is 330-lb, set last year [IIRC] by Mateusz Kieliszkowski of Poland, who was only 25 when he set the record.

The difference being - with the Circus Dumbbell, you can use both hands until you ultimately press the dumbbell. With the 240-lb "Inch Dumbbell" that Mark Henry pressed, you couldn't use more than one hand at all, for any portion of the lift.
With that in mind, and given the thickness of the dumbbell, the 240-lb was actually much more impressive than it would seem.
Henry was a strong dude! Generally speaking, the winner of the Arnold Pro Strongman is the strongman athlete who can legitimately claim to be the strongest man in the world, so if that standard applied in the inaugural contest in 2002, you could safely call Mark Henry the strongest man in the world [powerlifters aside - but that is open for debate].
