"Mork & Mindy" was a spin-off from an episode of "Happy Days" seen in February 1978, in which an alien from the planet Ork landed on Earth and attempted to kidnap Richie. So popular was the nutty character created by Robin Williams that Williams was given his own series in the fall of 1978, and it became an instant hit. Mork was a misfit on his own planet because his sense of humor (he was heard to call the Orkan leader, Orson, "cosmic breath"). So the humorless Orkans sent him off to study Earthlings, whose "crazy" customs they had never been able to understand. Mork landed, in a giant eggshell near Boulder, Colorado. There he was befriended by pretty Mindy McConnell, a clerk at the music store run by her father, Frederick. Mork looked human, but his strange mixture of Orkan and Earthling customs - such as wearing a suit, but putting it on backwards, or sitting in a chair, but upside down - led most people to think of him as just as some kind of nut. Mindy knew where he came from, and helped him adjust to Earth's strange ways. She also let him stay in the attic of her apartment house, which scandalized her conservative father, but not her swinging grandmother, Cora.
