* SugarWiki/AwesomeMusic: See [[AwesomeMusic/{{Film}} Awesome Music: Film]].
* 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 ''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 UsefulNotes/JoanOfArc, Ted briefly mimics the well-known picture of 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 ''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!"]]
* TheScrappy: Captain Logan. He has so little faith in Ted, that he already signs him up for Oats Military Academy without even giving him a chance to take his history exam. Needless to say, [[MissingMom if Ted's birth mother divorced him]], it's not hard to see why. He gets worse in the sequel, where the boys turn twenty one and he invites along Colonel Oates to their party, who immediately threatens Ted with being recruited to the Academy - despite Ted now being of the age where his father couldn't send him unwillingly.
