* AlternateCharacterInterpretation: Happens in-universe in the Season 1 episode "Aboard the Orient Express." Max protests against the Chief sending 99 on a dangerous assignment to deliver a briefcase. After hearing the Chief tell her how only the agent receiving the case has the key to open the handcuffs, Max ends up handcuffing the briefcase to his own wrist. Was this just Max making one of his usual ditzy mistakes, or was it, as 99 assumes, a deliberate ploy to protect her by making sure he would have to make the delivery instead of her? The "Hmmm..." look he gets in his eyes right before picking up the handcuffs suggests she may be right.
* {{Anvilicious}}: Subverted/parodied. In one episode, after Smart [[ItMakesSenseInContext blew up the bad guy with a cigarette]], 99 ponders whether or not Control's methods are [[NotSoDifferent any better than those of KAOS]]. Max's response?
--> "What are you talking about, 99? We have to shoot and kill and destroy. We represent everything that's wholesome and good in the world."
* EarWorm: [[InstrumentalThemeTune Da da daaa, DAA! Da da daaaaa, DA!...]]
* FairForItsDay: The episode "Washington 4, Indians 3" is rather cringeworthy by today's standards. However, it supports the Native Americans and shows understanding of their situation, if not their culture. [[spoiler: In the end, Max agrees that the White House should be attacked.]]
* GermansLoveDavidHasselhoff: The series was and still is popular in Mexico, thanks to the excellent dubbing work of the almost all the Mexican voice cast, to the grade that Maxwell Smart's Mexican VA, Jorge "el Tata" Arvizu, reprised his role as Smart in the Mexican Spanish dub of the 2008 movie.
* HilariousInHindsight: In "The Impossible Mission," Max gets his assignment in the form of a tape recording from the Chief, which ends with the warning, "[[InspectorGadget This tape will self-destruct]]."
** In "Too Many Chiefs," the MasterOfDisguise villain pretends to be the Chief and confuses Max by changing the TrustPassword.
--->[[AppleMacintosh "I say 'apple,' you say 'Macintosh.'"]]
* MemeticMutation: Pretty much every CatchPhrase the show brought us.
* OffscreenMomentOfAwesome: 99 giving her kidnapper a black eye and effortlessly escaping from her cell undetected in "And Only Two 99."
* SomeAnvilsNeedToBeDropped: The Cold War was often about this insane and stupid.
* UnintentionallySympathetic =/= UnintentionallyUnsympathetic: TheMovie version of Larabee is definitely a JerkJock... but it's hard to see Bruce and Lloyd the nerdy analysts he's feuding with as any nicer. Not only are they very petty in their revenge, the methods they use are often nastier than the verbal jabs Larabee delivers. They also gloat arrogantly about how obselete the field agents are going to be as soon as their robot comes in.
* WeirdAlEffect: The TV series parodied other spy shows airing at the time, such as ''Series/TheManFromUNCLE'', ''Series/ISpy'' and ''Series/TheAvengers'', but has been in reruns so long that most people assume it to be a ''Film/JamesBond'' parody.
* WhatAnIdiot: In TheMovie, just before the skydiving sequence, when 99 discovers that Max has dropped out of the plane without a chute, she suits up, and goes after him... Leaving behind the second parachute. TheDragon takes advantage of this lapse of judgment.
** The somewhat subtle joke that leads up to that scene where Max attempts to use the crossbow hidden in his pocket knife to undo his bonds, completely oblivious to the fact that ''he's holding a pocket knife''.
* WraparoundBackground: Not in the letter, but at least in the spirit, when Max goes with someone else from Room A through false backdoor A into Room B through false backdoor B into Room C...(it's always the same).
