He once kissed a female contestant on the show for good luck despite his mysophobia. He now takes medicine to control his condition and even pokes fun at himself for it. He revealed on The Howard Stern Show on March 24, 2006 that his shaved head is not related to natural hair loss, but to his mysophobia. He stated that the lack of hair makes him feel cleaner.[9] During his appearance on Mad TV, Mandel and cast member Bobby Lee made fun of the former's OCD. In September 2007, former NFL running back Marshall Faulk was interviewing with Howie on NFL Network asking him to shake his hands, but Howie wouldn't allow it; he'd rather have the fist tap, as he does with Deal or No Deal contestants. Seconds later, Faulk gave Howie a "sneak attack" shaking his right hand and Howie screamed in fear and walked away from Faulk. Howie washed his hands several times. On a guest appearance on Free Radio, Mandel explained that not only is he afraid of public bathrooms, but he is unable to use any bathroom other than his own.
