HBO had a special on him from the Venetian a couple of years ago. He talked about how he was looking for a picture album for all of the flyers that were given to him by the porn slappers.
I actually liked him on MNF. He added a much needed sense of humor to the games and his intro at the beginning of the game had me laughing out loud. I will agree that his references are often obscure, but I am old enough to "get" most of them.
