- Crowning Music Of Awesome: The rock video ALF recorded for Lynn.
- The second opening theme is very uplifting.
- Fanon Discontinuity:
- The made-for-TV movie, to some. Even if it does make for a much darker end to the series.
- Ditto for the aforementioned series finale.
- Germans Love David Hasselhoff: ALF is particularly popular in Germany, being one of the few 80's Dom Coms on public television that are easily accessible for children, as well as sporting a great dub. The series was so popular in Germany that the made for TV movie was even released to German movie theaters.
- Ditto in Mexico.
- It's one of the most popular shows of all time in the Ukraine.
- Harsher in Hindsight:
- The exchange between Alf and Jake in Shake, Rattle and Roll where Alf explains all the ways Jake could die in his own home and tells him that he loves him in case he doesn't see him again becomes unintentionally disturbing when one realizes that Jake never appears again after that scene.
- Willie Tanner not only acted as a conscience for Alf but also as a disciplinarian, having to lay down the law or even punish Alf when he went too far (which was frequently). Willie's actor Max Wright ended up getting in trouble with the law in the years after the series ended; he was arrested for drunk driving in 2000 and again in 2003.
- The Problem with Licensed Games: Well, the plot's similar to the E.T. Atari game for starters....
- Retroactive Recognition:
- The actress who played Raquel Ochmonek, Liz Sheridan, would end up becoming more well known for her role on Seinfeld as Helen Seinfeld, Jerry's mother.
- Dexter Moyers from the movie Project ALF was played by Miguel Ferrer.
- Steve Pepoon wrote 14 episode before co-creating The Wild Thornberrys. Two other co-creators of that show, David Silverman and Stephen Sustarsic, wrote six episodes of ALF.
- Victor Fresco wrote 11 episodes before going on to create and executive produce Andy Richter Controls the Universe and Better Off Ted.
- Al Jean and Mike Reiss wrote five episodes. Both went on to create and executive produce Teen Angel and The Critic.
- Donald Todd wrote four episodes well before making a name for himself as co-creator and executive producer of Samantha Who?.
- Kevin Abbott wrote an episode. Years later, he developed and executive produced the show Malibu Country.
- The military General who's after ALF in the series finale is Richard Fancy, who later will play Mr. Lippman on Seinfeld.
- Wangst: Lynn in the Season 2 episode "Varsity Blues". When she finds out that Willie and Kate can't afford to send her away to the college she wants; Lynn becomes very bratty and pouty. Fortunately, by the episode's end (after ALF reveals that he got a paper route to pay for Lynn's schooling) she realizes what a brat she's being and snaps out of it.
- What Do You Mean, It Wasn't Made on Drugs?. Subverted; Jerry Stahl freely admits his episodes were written on drugs, including the one where a giant cockroach tries to eat Alf.
YMMV / ALF
