Robert Blake
Robert Blake was preparing to host a 1982 episode of Saturday Night Live when he decided to tear up a script he was not satisfied with and then proceeded to throw it at writer Gary Kroeger’s feet. He was banned from the show. In 2001, he was charged with murdering his wife, so we’re sure the cast and crew of SNL were glad they didn’t have to work with him.
Fear
California punk band Fear were the musical guest on SNL on Halloween in 1981. They decided to get some slam dancers to mosh in front of the stage as they performed. Things got so out of hand that there was about $30,000 worth of damage (or even more) and the band was never invited back to perform again.
