It's impossible to shut up Kanye West. For God's sake the guy recorded a song with his jaw wired shut.
Also while we're exchanging Kanye ego stories I'll throw one in. Apparently he was scheduled to perform at this major concert in downtown with other bands like Pearl Jam in attendance. However Kanye wasn't on the stage he wanted to perform on so instead he decided not to do the show at all. My friend attributed the outburst to the fact that his mother had just died.
