March 30, 2008: At WrestleMania XXIV in Orlando, boxer Floyd Mayweather knocked out wrestler The Big Show eleven minutes into the bout.

Big Show dominated the majority of the match, despite frequent interference by Mayweather's ringside entourage. At the end, Mayweather hit Show with several steel chair shots, bringing the 7-foot wrestler to his knees. Mayweather then knocked Show out with a straight punch laced with brass knuckles.

Their feud began at WWE's pay-per-view No Way Out the previous month, where Big Show taunted Mayweather, who sat in the audience. Mayweather stormed the ring and broke Show's nose with some fast punches. Big Show challenged Mayweather to a WrestleMania match shortly thereafter.
