Howie Mandel Knuckles-Up

Everyone who remembers Howie Mandel from St Elsewhere knows how funny he is. What they dont know about Howie, is his fear of germs. Mandel never shakes hands with anyone. Instead, he knuckles up. When I hung out with Howie at The National Association of Television Producers(NATPE) he also informed me that if not for his wife, he would not have taken the job for Deal or No Deal.
