Eddie Murphy has finally revealed why he refused to play Bill Cosby on ?Saturday Night Live?s? 40th anniversary show. The legendary comedian, who was famous for his Cosby impression during his stint on the NBC variety show in the early 1980s, was supposed to imitate Cosby in ?Celebrity Jeopardy,? a skit fellow ?SNL? alum Norm Macdonald wrote and originally created. Kenan Thompson eventually played Cosby in the revived sketch. Despite the timelines of the topic, Murphy said he couldn?t stomach making jokes out of such a serious matter. He said in a recent interview, "There?s nothing funny about it. If you get up there and you crack jokes about him, you?re just hurting people. You?re hurting him. You?re hurting his accusers. I was like, ?Hey, I?m coming back to ?SNL? for the anniversary, I?m not turning my moment on the show into this other thing.'?
