It appears here that the writers are making in joke references to the movie Terminator, given that both Earl Boen, who plays Willy's boss, and Philip Gordon, who portrays Luis, were in it. ALF says to Luis "Hasta la vista", while Willy then tells him "No Problem" - although the latter might only have been from Terminator 2, which did not come out for another four years, and was given in that film in Spanish as "No Problemo".
