 Hotline Radio, Saturdays, noon to 2. Comedian and actor Martin Mull appeared in nearly 40 films and more than 50 shows. From the boss of the titular character, Roseanne, to the private eye in Arrested Development, and the vice principal of Sabrina the Teenage Witch. But perhaps most known for his role as Colonel Mustard in the murder mystery, Clue. I can't take any more scares.
