Marc Summers may not be a name that rings a bell to most people, although he has hosted numerous cable-television shows, most notably Double Dare (1986–88) on the Nickelodeon network. The participants in that game show for kids invariably ended up covered in goop, schmutz, and slime. The title The Life and Slimes of Marc Summers pays tribute to that calling card, but it also reveals the celebrity’s battle with obsessive-compulsive disorder (OCD), a malady that he has had since childhood.
