Lost on Earth

[1][2] It centers on a group of aliens who took the form of puppets after catching broadcasts of The Muppet Show and a reporter who's forced to work with them on a TV series.

KTEE-TV television reporter David Rudy (Tim Conlon) has just suffered an on-air gaffe that could cost him his job.

Rather than be fired, Rudy accepts a demotion from his boss, George Greckin (Paul Gleason), by agreeing to host a children's puppet show.

Rudy quickly discovers that the puppets are not props, but are real aliens that became stranded on Earth while exploring the universe.

[3] Claude Brooks of The Palm Beach Post said the series "isn't that bad", however "the puppets are funnier than the humans".
