Ugh.  Maybe I outgrew him, I dunno.  I liked him fine when I was in high school, even in college.  I liked the guests, and especially his bits.
Slowly, as he got bigger and bigger, with more A-list guests, he got more smug, and arrogant.  The bits stopped.  The talk was always about sex or boobs or shaving.  It got old.  Then he got divorced, got a HUGE paycheck, and starting living the true celebrity life, complete with a Hamptons mansion and invites to P. Diddy's parties.  
He became unrelatable and boring.  I much prefer the two local guys here in Philly.  I either listen to them or to the local sports talk station.
