* EnsembleDarkhorse: Exidor, the only character who could steal a scene from '''''Mork himself'''''.
* HarsherInHindsight:
** In one of his appearances, Exidor goes on a long spiel extolling the virtues of O. J. Simpson.
** In "Mork vs. the Necrotons", it off-handily mentioned by Captain Nirvana that the Necrotons could torture information out of Mork by rapping a rope round his neck, among other means. RobinWilliams died by suicide from hanging.
** At the end of "Mork in Wonderland: Part 2," Mork had only one wish upon reuniting with Mindy after her microworld counterpart, Mandy, died in his arms: for he himself to die before Mindy so he doesn't have to lose her twice. In a manner of speaking, Mork got his wish with Robin Williams dying in 2014 with Pam Dawber still around in good health.
* HilariousInHindsight:
** This setting [[TabletopGame/{{Warhammer40000}} isn't the only one]] that involves an alien called Mork.
** As mentioned above, [[TheCuriousCaseOfBenjaminButton Mork aging in reverse and what it means for his relationship with Mindy.]]
** After he turns himself old to cheer up Cora, he invites her to go to a [[NightAtTheMuseum museum]].
* RetroactiveRecognition: DavidLetterman turns up in one episode as a fraudulent self-help guru.
** After the show ended Mr. Bickley apparently [[Series/{{Newhart}} moved to Vermont and became a handyman at an inn]].
** Morgan Fairchild, who later carved a successful niche playing RichBitch characters in '80s {{Prime Time Soap}}s such as ''Falcon Crest'', played Susan (Mindy's ex-classmate and romantic rival) in season 1.
** Many actors who played minor characters had appearances on other shows in the '80s. A few examples: Jay Thomas later appeared as Eddie Lebeck on ''Series/{{Cheers}}''. Joe Regalbuto (a bad alien) went on to ''Series/MurphyBrown''. A very young Corey Feldman (''Film/StandByMe'', ''Film/TheLostBoys'') appears as one of Mork's day-care charges in a couple episodes. Dinah Manoff (''Series/{{Soap}}'', ''Series/EmptyNest'') plays a woman who tries to extort Mork in the second season.
* SeasonalRot: Despite the show being a hit in its first season, changes were implemented in season 2 as a bid for younger viewers. Several characters - including Mindy's father and grandmother - were dropped, Mork and Mindy getting together received greater emphasis, and episodes had an altogether different tone. Coupled with a new timeslot, ratings fell, which led to attempts at getting back to basics.
