Willie has a brother named Rodney.
(ALF is left alone in the house with the giant cochroach.) ALF: The only thing we have to fear is fear itself. Whoever said that must've had a lot of bodyguards.
(Willie goes to check on the roach after spraying it with insecticide.) ALF: How big did it get? Willie: That depends. Do you measure the shoulders or the head?
Kate: Ahh! A cockroach! Brian: Look it has blue eyes? Lynn: Yes. ALF: Naturally, it is a cockroach.
ALF(to cockroach): Look. You're angry at the world. I understand that. Uh, you probably didn't get enough love as a larva. Uh... b-but I got an idea. We can sit down. Talk. Have a nice cold glass of "boric acid". You know, we can deal with it. (reaches for a plunger) What you ya-What do ya think about that? (picks up plunger) Ever see one of these?!? Huh? Take that! (plunger breaks) Uh... Oh, I was only kidding. Joke! Joke!
When ALF muses, "The only thing we have to fear is fear itself," he alludes to the first inaugural address given by Franklin D. Roosevelt.
They joke about needing Sigourney Weaver for defeating the cochroach. That's an allusion to Weaver's role in the 1979 movie Alien, where an alien hides aboard a spaceship and kills off all but one of its crew.
The title is derived from a traditional Mexican folk song with the same name.
