Andy Kaufman
Andy Kaufman was a frequent guest on Saturday Night Live throughout its early years. By 1982, however, Kaufman’s contentious stage act had made him a divisive figure. In response, the show held a phone-in poll in January 1983, during which viewers could vote on whether the show “kept” or “dumped” Andy. Despite the fact that several cast members campaigned for the “keep” choice, “dump Andy” won with 195,544 votes to “keep’s” 169,186.
Robert Blake
In 1982, actor Robert Blake was barred from ever returning to SNL after tearing up a script he didn’t like and throwing it at writer Gary Kroeger’s feet while preparing to host an episode. Given that Blake was eventually charged with murdering his wife in 2001, we’d say the ban was for the best.
