Continuity mistake: At the beginning of the episode, Mrs. Tanner scolds her son Brian for dumping all of the clothes from the clothes basket. When she first scolds him the basket is white; it cuts again to her, and now the basket is brown and a different shape, too.
Continuity mistake: After Willie takes Alf into the kitchen to talk to him about someone at the Halloween party might realise that he's an alien, notice the zipper on the front of Alf. Out of nowhere, during one cut, a piece of black tape appears at the top of the zipper going across the top of Alf's chest that wasn't there before, then disappears in the next cut.
