Leave it to Vince McMahon to make a mockery of an already train wreck such as a Pro Bodybuilding show.
McMahon was the first to award $100,000 for winning a “train-wreck”. Dorian, Ronnie, Jay, and Dexter might not be getting the six-figure checks to go with their Sandows, had McMahon not done this.
Besides, nowadays, the IFBB guys are using props and costumes at their events. In fact, Toney Freeman has done that executioner routine several times. That's page from Johnnie "The Executioner" Morant's book.
