Was it the Doc who provided him with the mythical magic stick?
How about the Doc first sending Vince years into the future, and altering his genes with myostatin blockers or something? He could then send Vince back to 2004 and supply him with a sound diet, cardio, and training routine, as well as test, deca, gh, and anti-estrogens. Vince then does the 2004 Metrolina looking like Ronnie Coleman, then goes online and gives credit for his success to the supplements he sells at Caliber Fatness. His supplement business subsequently becomes the most successful of all time, making Vince a billionaire practically overnight. Internet History is totally reinvented, and the online world is changed forever!
