* CriticalResearchFailure: In an episode where Michael tries to find out if his staff has been lying on their resumes, he confronts Paul with his claim that he has been involved in a Jordanian election, suggesting that it can't be right, since Jordan is a monarchy. While the king of Jordan does retain much personal power, the country has multi-party politics and the Jordanian House of Representatives is democratically elected.
* FunnyAneurysmMoment: "Age Against the Machine" features Charlie ultimately deciding that he's too old to party every night. If only Creator/CharlieSheen had come to that same conclusion...
* HoYayShipping: Stuart & Carter eventually started acting more and more like this. Unusual mainly because Carter ''was'' gay. Became very, ''very'' close to canon at times. (Carter's nightmarish ImagineSpot about ending up with Stuart, miserable together until death, is probably a crowning example.)
** More and more? It already started in the second episode, with Stuart asking Carter on a date (ItMakesSenseInContext).
** Carter eventually starts questioning whether or not his feelings for Stuart are romantic. Asked to testify that he isn't in love with Stuart, he stammers that he "doesn't know" ... and also doesn't actually deny that they've been sleeping together.
* HilariousInHindsight: In one episode Mike and his crew accidently hires an interpretor for deaf people, who fakes his sign language, angering the deaf community. This later happened in RealLife [[http://www.cbsnews.com/news/mandela-service-interpreter-for-deaf-accused-of-faking-it/ at Nelson Mandela's funeral in 2013]].
** From "The Spanish Prisoner." Caitlin tells Charlie, "You're so self-confident, so self-assured, with so little reason to be that way." Considering the kind of smug {{Cloudcuckoolander}} Sheen would later become ("Tiger Blood", "Winning")...
** On "How to Bury a Millionaire", Paul wins the top prize on Series/WhoWantsToBeAMillionaire. Three days after the episode's original air date, John Carpenter became the first top prize winner on the real show.
* RetroactiveRecognition: [[Series/{{Firefly}} Malcolm Reynolds]] was a [[spoiler:gay]] personal trainer in New York.
** [[Film/TheSpirit Denny Colt]] appeared in one episode as a nudist campaigning for naturist's rights.
** Jorge Garcia (Hurley from ''{{Lost}}'') appears briefly as a taxi driver in one of Michael J. Fox's TheBusCameBack episodes.
* TheScrappy: Caitlin. To a lesser extent [[ReplacementScrappy Charlie]] qualify too.
* {{Tearjerker}}: The fourth season finale certainly qualifies. This is emphasised by the fact that the show's usually upbeat music is replaced with sad motifs and themes, and there is a reprisal of 'Everybody Gets What They Deserve' by The Churchills, which was used in a heartwarming moment in Season 3.
** It's even more of a tearjerker if you consider that Michael J. Fox only left because of [[GameBreakingInjury Parkinson's]]. Otherwise the show might have continued.
