Claim To Fame: This foul-mouthed schlub rose to fame in the Nineties as the Laverne to Dr. Drew's Shirley on MTV's dating call-in show Loveline – that is, if Laverne often came under fire for misogynistic remarks and Shirley was a fame-whore justifying his actions under the guise of medical guidance. Carolla also co-hosted Comedy Central's The Man Show with Jimmy Kimmel, but only one of them was able to use it as a springboard to major success. We’ll let you guess who that was.
What To Expect: Carolla is a reality TV producers' dream: he's loud, obnoxious and doesn't think before he speaks – very similar to the Celebrity Apprentice's host, in fact. Common logic dictates that Carolla's teammates won't put up with his funny-guy shtick, and either will Trump. Chances are we won't be seeing much of Adam.
