Manny Pacquiao followed behind 50 Cent by coming at longtime nemesis Floyd Mayweather's education during a recent interview with The Star-Ledger. 

Pacquiao kicked things off by denigrating Mayweather's undefeated record. The Filipino boxer said that Mayweather's string of wins don't amount to much, because he believes the contenders aren't the best in the game.

"Well, I think he is worried about his record. He talks about his zero losses. The zero that means so much to him means nothing when measured against who he fought. You talk pound-for-pound best, or undefeated champion. If you don't defend against the best, none of that means anything." 

Pacquiao then took shots at Mayweather's education. "[He is] not [scared] of fighting, but perhaps of what one night could do to his zero of losses. I think I finally understand him:...what he says,...how he acts,...and I don't like it. But what l learned and heard from him, well, I realize why he is like that. I understand sometimes when the people are not educated they just talk to talk. He sets a very bad example."
