Mork appears in the "Happy Days" season five episode "My Favorite Orkan", which first aired in February 1978 and is a take on the 1960s sitcom "My Favorite Martian". The show wanted to feature a spaceman in order to capitalize on the popularity of the then recently released "Star Wars" film. Williams' character, Mork, attempts to take Richie Cunningham back to his planet of Ork as a human specimen, but his plan is foiled by Fonzie. In the initial broadcast of this episode, it all turned out to be a dream that Richie had, but when Mork proved so popular, the ending in the syndicated version was re-edited to show Mork erasing the experience from everyone's minds, thus meaning the event had actually happened and was not a dream.
