Out of the Blue.

Out Of The Blue is an American fantasy sitcom that aired on ABC during the fall of 1979. It is chiefly notable as having featured a Mork & Mindy crossover, and for the controversy surrounding its status as a spin-off of Happy Days. The series stars Jimmy Brogan as Random, an angel-in-training who is assigned to live with a family and work as a high school teacher. The series aired from September 9 to December 16, 1979. Nine episodes had been aired at the time of cancellation. Some completed material was never broadcast.
