Johnny Jupiter is the name of two early American television programs featuring a combination of live action and hand puppets.

[1] The original version, broadcast live on the DuMont Television Network Saturday evenings for 30 minutes, from March 21 to June 13, 1953, starred Vaughn Taylor as an elderly janitor, Ernest P. Duckweather, cleaning-up after midnight in a TV studio.

The often sharp humor of the series was based on Duckweather trying to explain and justify earth customs to the natives of Jupiter, who could view them on their own TV sets.

The puppets appeared only when Duckweather needed help or advice; the magic TV set now brought in three Jovian hand puppets: Johnny Jupiter; a cube-headed robot, Major Domo; and a cylinder-headed, glasses-wearing Reject the Robot, all voiced by Gil Mack.

The solution to Duckweather's problem generally involved beaming the bumbling Reject to earth, where he was played by new puppeteer Gene (aka Phil) London wearing a large prop robot suit.
