* SugarWiki/AwesomeMusic: See [[AwesomeMusic/{{Film}} Awesome Music: Film]].
* CriticalResearchFailure: The RunningGag about Bill's full name being "Bill S. Preston, Esq.", implying that he's [[HiddenDepths more genteel and well-bred than he appears]]. But the honorific title "Esquire" specifically denotes that someone is an ''attorney''. So either our favorite teenage wastoid secretly has a law degree, or the writers just didn't bother to look up what "Esquire" actually means.
* FamilyUnfriendlyAesop: While the titular duo are messiahs who usher in a peaceful utopia with their music, they get to that point by using time travel to manipulate their lives for the better, making this a benign but still prevalent case of UtopiaJustifiesTheMeans.
* GeniusBonus:
** UsefulNotes/SigmundFreud's corndog-on-a-stick gag.
** When Freud is coming on to some girls, he tells them that they "seem to be suffering from a mild form of [[GettingCrapPastTheRadar hysteria]]."
** The references to ''Film/TheSeventhSeal''.
** The guys spotting some weakness in Napoleon's plan for the Battle of Waterloo. Made funnier because their tone implies they're ''not'' using historical knowledge; two idiots just noticed a flaw that the emperor didn't.
** When they pick up UsefulNotes/JoanOfArc, Ted briefly mimics the well-known picture of [[Art/SistineChapel God and Adam from the Sistine Chapel]].
** UsefulNotes/GenghisKhan is shown forcefully making out with a servant girl - why do you think he supposedly has descendants across half of Asia?
** That scene where Napoleon's thrown out of the bowling alley? Instantly familiar to anyone who's seen the 1927 film ''Film/{{Napoleon}}''.
* MemeticMutation
** "Be excellent to each other... and party on, dudes!"
** "Strange things are afoot at the Circle K."
** The Wyld Stallyns guitar riff and accompanying hand motions.
** The picture for [[http://knowyourmeme.com/memes/conspiracy-keanu Conspiracy Keanu]] comes from ''Excellent Adventure''.
** "San Dimas High School football rules!"
* ValuesDissonance: When Bill and Ted hug, they always push each other away and humorously shout "Fag". This was okay for an 80's movie that was rated PG. That term is less acceptable now. The same goes for the sequel, where the guys attempt to talk the Evil Robot Usses out of killing them by saying "We love you!", prompting the [=ERUs=] to say "Fags!" and then kill them anyway. Though that might have slipped under the radar because [[{{Mondegreen}} it kind of sounds like a sarcastic "Thanks!"]]
** It also helps that, with the real Bill and Ted at least, they don't seem to have any hurtful intent with the use of the word and it's just one of their many jokes between them. Even today using offensive terms jokingly between friends who know each other well enough to not be offended is not uncommon.
