Robert Schimmel, the caustic comic known for his candid talk about his health and personal problems on the Howard Stern Show, has been arrested, the Daily News reports.

Stand-up comedian Robert Schimmel was busted for allegedly beating up his wife, TMZ reported Saturday.

The X-rated funnyman was being held on $50,000 bail after cops were called to his home in Los Angeles and found his wife roughed up, the Web site said.

Schimmel, 59, is known for his off-color humor and his battle with non-Hodgkin’s lymphoma, which he chronicles in his new book, “Cancer on $5 a Day.”

He divorced his first wife, Vicki, three times, then married his daughter’s best friend, Melissa, who is half his age. They have two children.
