Johnny Jupiter - Alien puppet character from the planet Jupiter who communicated with Earth via interplanetary television transmissions on the JOHNNY JUPITER/DUM/1953-54. His earthly contact is Ernest P. Duckweather, a janitor of a TV station (later a store clerk), who accidentally picked up Jupiter's wavelength when tinkering with a television console. Johnny had a head shaped like a peanut with a small antenna sprouting from the top of his noggin.

Speaking with a British accent, Johnny eavesdropped on the planet Earth by monitoring Earth's television broadcasts. He questioned our strange habits and customs.

Commenting on television, Johnny informed us that on Jupiter television was used for punishing children when they spent too much time reading books or playing with slide rules.

Other alien puppets that talked with Earth included B-12, Major Domo, and Reject the Robot.

The series was a satire of Earth as seen through the eyes of the alien, Johnny Jupiter.

The role of E. P. Duckweather was played by Vaughn Taylor and Wright King. The hand puppets were animated by Carl Harms.
