Nick Cannon GOES IN on Eminem...(VIDEO)

A preview clip from the Nick Cannon's first-ever stand-up comedy special has found its way to the 'Net. In the clip, Nick discusses his grandfather's reaction to his and wife Mariah Carey's much-publicized beef with Eminem -- or "Enema," as Grandpa Cannon calls him. Gramps has his own opinion on how to handle the situation -- and it doesn't involve Twitter.

Nick Cannon: Mr. Showbiz will premiere at 9:00 p.m. this Saturday on Showtime.
