* {{Anvilicious}}: "The Golden Triangle", "To Be A Man"
* CrowningMusicOfAwesome: The main theme not only sounds, well, ''[[ExactlyWhatItSaysOnTheTin Awesome]]'', but it also sums the show up about as perfectly as any lyricless tune possibly could. The subdued electronic intro is accompanied by scenes of someone fiddling with gizmos and sciency stuff, segueing in to a shot of a bomb timer counting down as the volume rises, before the show title literally explodes on to the screen and the main theme begins to accompany a montage of thrilling action shots. Wow! Makes [[JamesBond James Bond]] Walking along before turning to shoot someone seem pretty damn lame by comparison.
* 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]]. See 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.]]
* MomentOfAwesome: The entire opening gambit of "The Gauntlet."
* {{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.
