Robert Blake. Decades before he was accused of murdering his wife, actor Robert Blake was accused of being a complete grouch behind the scenes of SNL. He allegedly butted heads with the cast, producers, and writers prior to his November 13, 1982 hosting gig, even throwing a script in the face of cast member and writer Gary Kroeger. Blake fulfilled his obligation to host that episode in season eight, but never returned to the SNL stage.
