When ALF is saying his goodbyes to everyone, he says, "Good night Mrs. Ochmonek, wherever you are." This was a reference to the line Jimmy Durante used to say at the end of his radio program, "Good night, Mrs. Calabash, wherever you are!"
ALF's Melmacian name is Gordon Shumway. He turned 228 the day his planet exploded.
This is the first episode to feature Melmacians other than ALF.
