“America’s Got Talent” judge Howie Mandel isn’t busy enough.

The germaphobic comic has just bought a reality-show idea from Danish TV and is making an American version of a show called “Celebrity Stand-Up,” according to the Hollywood Reporter.

The show — a sort of “Joking With the Stars” format — follows a group of celebrities for five days as they develop a personal story about their lives in a stand-up comedy act.

A live audience then decides which celeb is the funniest and sends them on to the next round.

Mandel is developing the show himself — though he has not yet sold the show to a network.

Mandel, the former host of “Deal or No Deal,” was the only celeb on the “Talent” panel with only one job.

Fellow judge Piers Morgan also has a daily interview show on CNN and Sharon Obourne is a co-host of the afternoon talk show “The Talk.”
