The Ultimate Vampire Resource and Directory

The Lost Saucer was about two time-traveling futuristic androids named Fi (Ruth Buzzi) and Fum (Jim Nabors) who land their flying saucer on present day Earth. They inexplicably invite a young boy named Jerry (Jarrod Johnson) and his babysitter Alice (Alice Playten) to check out the interior of their craft.
As onlookers begin to gather, the two androids become nervous about attracting attention, and abruptly take off with Jerry and Alice. The flying saucer has the ability to travel through time, and the controls which allow the androids to specify an exact date becomes damaged, thus preventing the androids from returning Jerry and Alice to their rightful time and place. The series follows the foursome as the two androids (who bicker and argue incessantly with each other, neither seeming competent with the ship's controls) encounter various adventures while trying to return Jerry and Alice back home.
