Coulier, who had aspired to be a hockey player but was sidelined by injury, got his start in comedy by cracking up his classmates in the school cafeteria. He soon produced an evening in a local hall that attracted 900 paying customers. A stint at a local radio station writing and voicing commercials followed. He started doing stand-up at local clubs in Detroit and, on the advice of a comedian he opened for, moved to L.A in the late 1970s. Taking a job as a doorman at LA's Comedy Store, he soon got stage time and became a regular. On the basis of voice tapes he submitted to an agent, Coulier landed voiceover work with several animated series including "Scooby Doo" "Mork & Mindy", "The Muppet Babies" and "The Real Ghostbusters". He made occasional appearances on episodic TV and hosted the cable series "Out of Control" and "Kids' Choice Awards" (both 1990). He co-wrote and co-starred on the ABC Special "Inside America's Totally Unsolved Lifestyles" (1992).
