If you're of a certain age, you probably have fond memories of Nickelodeon's popular '80s and '90s shows "Double Dare" and "What Would You Do?" hosted by Marc Summers.

Every episode invariably featured lots of slime, goo, cream pies, a vat of beans, whatever. Kids loved it.

But Marc Summers was silently suffering.  

As he told me in our 1999 interview, he has OCD -- Obsessive Compulsive Disorder -- which makes him super uncomfortable when things get messy or dirty -- or slimy.
