Robert Guerrero will box Floyd "Money" Mayweather on pay-per-view this Saturday night. Pre-fight boxing press conferences tend to be predictable. One fighter trash talks another. A promoter will over sell the fight like it's going to be the reincarnation of "Ali vs. Frazier."

Occasionally something unpredictable occurs. Robert Guerrero’s father, Ruben, took to the mic at today's pre-fight press conference. He got a few chuckles in the crowd, then started screaming "woman beater" toward Mayweather, and he didn't stop there. From that point on, the presser suddenly became unpredictable...and extremely awkward.
