The Date: September 2011
The Crazy Moment: After knocking Victor Ortiz down and getting the 42nd win of his professional career, Mayweather threw some shots at HBO's Larry Merchant, who got so riled up by Mayweather's comments that he said, "If I was 50 years younger, I'd kick your ass!"
Why It Was So Wild: Everyone who paid $60 to order the Mayweather/Ortiz pay-per-view fight was understandably upset by the way the fight ended. But the bizarre back-and-forth between Mayweather and Merchant was easily worth the price of admission. As usual, Mayweather knew how to give people their money's worth. Well done, champ.
