* SugarWiki/AwesomeMusic: See [[AwesomeMusic/{{Film}} Awesome Music: Film]].
* CrazyAwesome: The actual makeup of the band:
** Lead singers/guitarists are time traveling rock and roll messiahs.
** Bass player is [[TheGrimReaper Death]]. Literally.
** Bongos played by the most intelligent being in the universe, which happens to be two (sometimes) Martians.
** Drummer and Keyboardist are [[EverythingsBetterWithPrincesses medieval princesses]]
** Backup dancers are super-strong robot versions of the leads, built by the bongo player(s).
* EnsembleDarkhorse: William Sadler as Death, constantly struggling to hold on to the remains of his shattered dignity.
* 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:
** Sigmund Freud'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 ''The Seventh Seal''.
** 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 JoanOfArc, Ted briefly mimics the well-known picture of God and Adam from the Sistine Chapel.
** 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 ''Napoleon''.
* HilariousInHindsight: How ironic that Jim Martin of FaithNoMore, "founder of the Faith No More Spiritual and Theological Center", ''quit'' Faith No More only two years after his appearance in ''Bogus Journey''.
** William Sadler plays Death in the second film and performs a HeelFaceTurn when Bill and Ted defeat him. A few years later in ''Film/DemonKnight'', he plays TheChosenOne that battles the forces of Hell to stop them from conquering the universe.
* ItWasHisSled: The fact that Rufus's future is based on Wyld Stallyn's music is a bit of a [[TheReveal Reveal]] at the end of ''Excellent Adventure'', but anyone explaining the plot mentions it right away.
** Not exactly - Rufus does mention in the opening blurb that it's thanks to Bill and Ted's music that the future is what it is, and that it very nearly wasn't the case. The film further emphasises the importance of Wyld Stallyns when they accidentally visit the future and get another hint of their importance.
* 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!"]]
*** The sequel might actually be [[LampshadeHanging hanging a lampshade]] on the word not being acceptable to use. After all the ones using it are the ''evil'' Bill and Ted, who are overall more immature and [[{{Jerkass}} mean]] than the real thing. The real Bill and Ted hug in the sequel without a real problem, indicating they've grown up a bit.
* WhatDoYouMeanItsForKids: The sequel. Take a lighthearted, family-friendly TotallyRadical comedy and add lots of terror along with a PlayedForLaughs´ - yet still effectively morbid´ - DisneyDeath plotline, heavily ramped up profanity, sexual dialogue and incest references, and quite a few instances of HoYay as well, and you've got something that probably didn't sit nearly as well with the original film's target audience.
