ALF

From Wikipedia:

ALF is an American science fiction sitcom that originally ran on NBC from 1986 to 1990 and was created by Paul Fusco. The title character was Gordon Shumway, a friendly extraterrestrial nicknamed ALF (for Alien Life Form), who crash lands in the garage of the suburban middle class Tanner family.

The series stars Max Wright as father Willie Tanner, Anne Schedeen as mother Kate Tanner, and Andrea Elson and Benji Gregory as their children, Lynn and Brian Tanner. The character of ALF was portrayed by a live-hand puppet operated primarily by Fusco.

Premise

ALF (Paul Fusco) follows an amateur radio signal to Earth and crash-lands into the garage of the Tanners. The Tanners are a suburban middle class family in Los Angeles, California. The family consists of social worker Willie (Max Wright), his wife Kate (Anne Schedeen), their teenage daughter Lynn (Andrea Elson), younger son Brian (Benji Gregory), and their cat Lucky.

Unsure what to do, the Tanners take ALF into their home and hide him from the Alien Task Force (a part of the U.S. military) and their nosy neighbors Trevor and Raquel Ochmonek (John LaMotta and Liz Sheridan), until he can repair his spacecraft. He generally hides in the kitchen. It is eventually revealed that ALF's home planet, Melmac, exploded because of a catastrophe involving nuclear war. In episode four of season one ALF tries to convince the president of the USA to stop the nuclear program as ALF is afraid that Earth might suffer a doom similar to Melmac's. ALF was off the planet because he was part of the Melmac Orbit Guard. ALF (a.k.a. Gordon Shumway) is homeless, but he isn't the last survivor of his species. He becomes a permanent member of the family, although his culture shock, survivor guilt, general boredom, despair, and loneliness frequently cause difficulty for the Tanners.
