i dont think he's a genius, but i do think he's quite good at what he does. he's funny. he may not hit 100% of the time, but who would given his exposure.. 20+ hrs a week. he has influenced radio but not to the extent that he claims. hell, if you listened to him, you'd have to think that he invented anal sex.
as far as people going all high brow on this. yeah, he can be rude and crude, but i'd be very surpised if all those people in the world who says he is nothing but immature and lame didnt laugh at some antics.
