Out of the Blue was a short lived series from the Happy Days Conglomerate (although some debate exists as to whether or not it's a spin off, I honestly don't care). Most of you may remember the annoying episode where Chachi sells his soul and an angel comes to help. It's pretty much a religious variation on the Mork episode just not as headache inducing.
The series that resulted, was the Mork formula through and through, a magical being played by a stand up comic (in this case Random the angel played by comedian Jimmy Brogan) comes to live with a family of orphans living with their aunt (a pre "Designing Women" Dixie Carter) and keep his magic powers a secret. Oh, did I mention hilarity ensued?
It didn't last very long, from what I can remember it was a pretty unspectacular series.
You can see the original opening on Retro Junk, I was depressed at how much I remembered.....
