An inept angel named Random was sent to Chicago to help a harried aunt deal with her five nieces and nephews, after their parents were taken in a plane crash.
To help with expenses, Aunt Marion accepted Random as a boarder. Unbeknown to her, Random was also an angel with magical powers -- however the children knew his secret. Random would often use his powers to teach the kids little lessons about growing up.
I have read all the rumors about this show. Some people say that it is a spin-off of Happy Days, some people say it's a spin-off of Mork and Mindy, and some people even say it was just a show on it's on that has crossovers with these two shows. The pilot episode which aired on Happy Days aired after the second episode of Out of the Blue because of pre-emption, but it originally was supposed to serve as the pilot. This show lasted for seven episodes plus at least one postponed and un-aired episode (nine counting the pilot on Happy Days).
2nd editor's note. It seems clear the Random character (and the actor) was tested on Happy Days, with the episode being held back until after the series was approved for the new fall season, actually airing more than a week after the first episode of Out of the Blue premiered.
To further gather an audience, the producers added Mork from "Mork and Mindy" to the one hour season premiere. To quote TV Guide from that week, Random was "not the only other-worldly character in view tonight, the opener includes a visit from Mork from Ork (Robin Williams)".
The definition of Spin-off means that the show is produced after the intro in the series that spawned it, not that it is shown after that episode, so this series is clearly a spin-off of "Happy Days".
