Pissed there's a probability, But we all know what a class act Manny is. Remember the insults Margarito camp laid out of Roach? Manny's reply was "Roach be a gentleman, I'll take care of it"(inside the ring). And we all knew what happened.
Nobody has pushed and leaned on manny at a stare down. You can bet your ass mayweather will try it. And then there is the steroids thing
Floyd would be serious. Pac would laugh it off, then as they are eye to eye, Mayweather would call him out for him wearing shoes to a weigh in.
Similar to the Hatton stare down, Floyd talking trash in Manny's ear and the only response is to smile and listen
Pac would start laughing and then grab the mike and sing a karaoke song, Floyd would outdo pac and start rapping wid his girlfriend 50 cents.
Floyd's trash-talk won't hit Pacquiao as hard as it would someone else, but his brashness and disrespect will definitely urge Pacquiao to train hard and make a statement I think. He'll be serious come the stare-down.
At the night of the weigh in, Mayweather gives pac a serious look while pac looks away and laughs. Pissed off, Mayweather says Floyd: "You yellow midget poochiao gonna be ready with yo a-side meff and I'll whoop yo sorry ass tomorrow night" Pac, hearing what floyd said in his face, Pacquiao: "Hu are yu calling midgit, yu big-domed wuman-bitter?" *Waaaapakkkk* ...and there goes your Fight of the Century folks....
