ALF stands for "alien life form," and it becomes the adopted moniker of Gordon Shumway, the last known survivor of the planet Melmac; Gordon crashes his spacecraft into the garage of the Tanner family's suburban home, and is subsequently adopted by them. They must keep him out of the hands of the authorities, however, which means no one can ever know about the alien who lives with the Tanners, giving rise to many hilarious adventures. In the fourth and final season of this '80s classic, ALF almost loses baby Eric, becomes an artist, fights pollution, and catches his first cold.
