What planner hasn't shrunk in his chair at a crude joke told by a comedian he or she hired? Those who don't want to be blindsided by an off-color remark should consider Clean Comedians, whose motto is: “It doesn't have to be filthy to be funny.”

“Many of our best customers come to us because they got burned hiring a raunchy comedian from a club the previous year,” says Adam Christing, president of the La Mirada, Calif. — based company, which represents more than 100 entertainers, including stand-up comedians, comic- magicians, jugglers, and variety acts.

The company is so confident that its funny men and women will entertain without embarrassing that it offers meeting planners a money-back guarantee if they or their attendees are offended. Clean Comedians also has an “easy event planning” form on its Web site to help planners find the right jokester. For more information, go to www.cleancomedians.com.
