* {{Anvilicious}}: "The Golden Triangle", "To Be A Man"
* DryDocking: Nikki Carpenter was introduced as a possible love interest for Mac. However, the producers soon discovered that female fans did not want Mac to be permanently attached and Nikki was quietly {{Put on a Bus}}.
* EarWorm: The theme tune. Especially [[http://www.youtube.com/watch?v=bCkkWewbqtw the eighties version]], which also qualifies as CrowningMusicOfAwesome.
* EnsembleDarkhorse: Murdoc. No one ever wanted him to actually ''defeat'' [=MacGyver=], but fans loved to see [=MacGyver=]'s {{Indy Ploy}}s go up against Murdoc's CrazyPrepared.
* FamilyUnfriendlyAesop: Rough play is necessary in hockey. ("The Eraser")
* HilariousInHindsight: Any scene containing his future Stargate co-stars, especially the one where he throws Christopher Judge on the ground. Doubly funny when his character guesses a gadget is a "Martian toothbrush."
** Dr. Zito (W. Morgan Sheppard) [[Recap/DoctorWhoS32E1TheImpossibleAstronaut helping someone set up a mock Viking funeral]].
** As seen in the page quote, the first [=MacGyver=] joke is actually in the show's own first episode.
* HoYay: Mac and Jack had their moments.
* MemeticMutation: "MACGYVERRRRRRRRRRRRRRRRRRRRRRRRRRRRR!"
** He was a popular subject of parody on {{YTMND}}, blowing [[MacGyvering his contraptions]] to [[ExaggeratedTrope ridiculous proportions.]]
* {{Narm}}: Mac's reaction to [[spoiler:Booker]]'s death.
* TearJerker: [[spoiler:Mike's]] death moments after [=MacGyver=] rejected her.
** Subverted: [[spoiler:Mike]] fell to [[spoiler:her]] death during a mountain climbing expedition, and Mac's thrashing at the end of the rope as he tries to save [[spoiler:her]] was rather callously added to the opening credits.
