Piscopo’s comments come a day after Cosby’s spokesperson slammed Murphy on Instagram over the joke, calling him a “Hollywood Slave.”

During his monologue, Murphy joked that if you would have told him 30 years ago that “I would be this boring, stay- at-home … house dad and Bill Cosby would be in jail,” he would’ve taken that bet. Murphy then imitated Cosby, asking “who is America’s dad now?” Cosby was found guilty of sexual assault last year.

Piscopo, who was on "SNL" in the early '80s with Murphy and featured together in skits parodying people like Stevie Wonder and Frank Sinatra,  said he remembers when Murphy got the call from Cosby, whom he had always had "immense respect” for early on.

“Cosby just called me, man,” Murphy said, according to Piscopo. “He railed me for being too dirty – he railed me—he yelled at me for like 20 minutes.”
