45. Big Show vs. Floyd Money Mayweather WrestleMania 24
If LT versus Bigelow is the gold standard of celebrity matches at WrestleMania, Big Show versus Floyd Mayweather is a close second and a highly underrated bout. Show does not get nearly enough credit for making this entire feud work, and in a different world, Mayweather would be an outstanding heel. In some twisted reality, Mayweather was supposedly the hero standing up to a big bully, but if you just watch the buildup and match, Show was defending his way of life while Mayweather preened and leaned on his entourage to take on the giant. Mayweather still is arguably the biggest name in professional boxing, so to see him physically mix it up with Big Show seven years ago is an impressive sight.
