By 1989 "ALF" had the popularity of not only an animated spin off, but also printed issues from Marvel Comics.
Jim 'Jimbo' Hutchinson was one of the very few people that spent the night at the tanners that never met Alf.
Alf quotes the lyrics for the song "Billy, Don't Be a Hero" (substituting Willie for Billy), first a 1974 #1 hit in the UK for the band Paper Lace, and then a few months later a #1 hit in the US for the band Bo Donaldson and the Heywoods.
