* GeniusBonus: The reference book ''The Klingon Dictionary'' contains the word "[=ghIlaSnoS=]", defined as "an ancient political movement". "[=ghIlaSnoS=]" is pronounced something like "ghi-lash-nosh", which is close to [[https://en.wikipedia.org/wiki/Glasnost "glasnost"]] (and factor in that in ''Series/StarTrekTheOriginalSeries'' the Klingons were stand-ins for Soviet Russia).
* HilariousInHindsight:
** In issue #9 of the Gold Key Star Trek comics released in 1971, we are introduced to (a robotic replica of) the future 45th President of the United States, a man called Anton York. Who happens to [[UsefulNotes/DonaldTrump physically resemble the future actual 45th American President]]!
** A Deep Space Nine book released in 1999 is titled [[RuleThirtyFour The 34th Rule]]. Said rule is 'war is good for business,' but tell that to people today.
* TearJerker: In the [[EarlyInstallmentWeirdness early DS9 novel]] ''The Siege'', a temporarily impassable wormhole tears an incoming ship to shreds. When the crew scans the debris it turns out to have been a [[spoiler:[[TheDreaded Borg cube]]]]. When Jake finds out that the monsters that killed his mom have a shortcut to their doorstep, he [[HeroicBSOD freaks]] [[OhCrap out]] at Sisko over dinner and it takes all of Ben's not inconsiderable dad skills to calm him down.
