Controversy was buzzing around the 40th anniversary of “Saturday Night Live” as former cast member Norm Macdonald reportedly shared more than 100 tweets, typing out insider details of the show’s writing, cast dynamics and role choices. The most titillating story Macdonald shared was his knowledge of Eddie Murphy’s last-minute choice to not depict Bill Cosby in the “Celebrity Jeopardy” sketch.

Rolling Stone magazine reported, “At the tail end of the ‘Celebrity Jeopardy’ sketch—which reintroduced Darrell Hammond as Sean Connery, Will Ferrell as Alex Trebek and Macdonald as Burt Reynolds/Turd Ferguson—a Video Daily Double appeared in the Potent Potables category. Current SNL cast member Kenan Thompson played Bill Cosby, revealing his cocktail recipe, a nod to the sweeping allegations against the comedian.”

As Macdonald revealed on Twitter, that cameo was originally written for Murphy, who, after a few days of being pursued by Macdonald, Michaels and even director Brett Ratner (the latter serving as an intermediary for the comic), decided not to appear in the sketch.

“Murphy knew the laughs would bring the house down. Eddie Murphy knows what will work on ‘SNL’ better than anyone. Eddie decides the laughs are not worth it. He will not kick a man when he is down,” Macdonald wrote. “Eddie Murphy, I realize, is not like the rest of us. Eddie does not need the laughs. Eddie Murphy is the coolest—a rock star even in a room with actual rock stars.”

Soon after the news of Murphy’s respectful behavior broke, Cosby issued a statement through Andrew Wyatt of Purpose PR, saying, “I am very appreciative of Eddie and I applaud his actions.”

It is safe to say that Murphy took a moral stance in this instance. He has a history of experiencing disagreements with “SNL” staff, particularly a joke David Spade made about him, that kept him from participating in the show’s 25th anniversary. Murphy addressed his perspective of the comedy series in a 2011 Rolling Stone interview.

“Yeah, because they were sh—y to me on ‘Saturday Night Live’ a couple of times after I’d left the show. They said some shitty things. There was that David Spade sketch [when Spade showed a picture of Murphy around the time of ‘Vampire in Brooklyn’ and said, ‘Look, children, a falling star’]. I made a stink about it, it became part of the folklore. What really irritated me about it at the time was that it was a career shot. It was like, ‘Hey, come on, man, it’s one thing for you guys to do a joke about some movie of mine, but my career? I’m one of you guys.”
