Here’s Wikipedia’s synopsis of CBS’s short-lived TV series Meego:
Meego ([Bronson] Pinchot) is a 9,000-year-old shape-shifting alien from the planet “Marmazon 4.0”. After Meego’s ship crashes, he is discovered by three children; Maggie (Michelle Trachtenberg), Alex (Jonathan Lipnicki), and Trip Parker (Erik von Detten, later played by Will Estes). The children live with their single dad, Dr. Edward Parker (Ed Begley, Jr.) and pass Meego off as human (Meego does not want anyone to know that he is extraterrestrial, and tells people he is from Canada instead). Although Meego plans to leave Earth as soon as his space ship is repaired, he became attached to their children and decides to remain on Earth to care for the three Parker children. …
The show’s supporting cast also included some of the most recognizable child stars of the time period; Trachtenberg was the star of the film Harriet the Spy and Lipnicki had been seen in Jerry Maguire as well as several TV shows. (Von Detten would later go on to star in his own TGIF show, Odd Man Out, and have a supporting role in another, Complete Savages.) Despite this, the show was a complete failure: it ranked at #111 in the Nielsen ratings with 8 million viewers per episode. After six weeks, it was pulled from the schedule the following week in favor of a rerun of It’s the Great Pumpkin, Charlie Brown and was formally canceled shortly thereafter.
Oh dear.
