He is (or was) primarily known for blocking traffic on the Bay bridge while he got a haircut. That was back when he had a show in San Francisco and was around the same time Clinton tied things up getting his haircut on a plane in Los Angeles.
He went to Chicago or somewhere after that.
Mancow left his show in the San Francisco area not because he got fired for the haircut on the Bay Bridge - he AND the station were fined beaucoup $$$ - but because his father was dying of cancer and he wanted to be there emotionally supporting both his mother and father, during that time.
