What the hell is Michael Bisping's problem?

Has anyone else noticed Michael Bisping's act lately? He pretty much has been ragging on any fighter not named Michael Bisping. I'd love to see Bisping fight Stann, Belcher and Wiedman ALL ON THE SAME NIGHT! He then called out Mark Munoz for being fat at least three times in one interview. And most recently telling Joseph Benavidez that his 11-year-old could whip his ass. I know that you don't necessarily get into the fight game to make friends. But does anyone really need more enemies? Apparently Bisping thinks so as he's doing everything he can to piss off his peers.
