King Goshposh was created for Jim Henson's failed 1962 pilot Tales of the Tinkerdee, and also appeared in another pilot, The Land of Tinkerdee. Goshposh was a genially dunderheaded monarch, with a fondness for parties and presents. He spoke with a broad Texan accent.
Goshposh finally appeared on screen in the 1967 summer replacement series Our Place, appeared under the name "King Louie" on The Mike Douglas Show and in The Muppets on Puppets, had the name King Impossible the Third in Rumple Wrinkle Shrinkel Stretchelstiltzkin, and took a leading role as Prince Arthur Charming's father in the 1970 special Hey Cinderella! He later made an appearance in The Perry Como Winter Show in 1972, playing a hotel manager.
King Goshposh smoked a cigar in many of his scenes; unlike other Muppet cigar-chompers, his was actually lit. In his appearance on The Mike Douglas Show, conversing with Hermione Gingold, Goshposh explains that he has in fact lost his kingdom: "I blew it."
