* MemeticMutation: The scene where Banderas's character [[http://knowyourmeme.com/memes/antonio-banderas-laptop-reaction checks his computer]] has become a popular reaction GIF in the discussions about gaming news.


* EarWorm: And it's seriously a problem. "What a wonder is a gun! What a versatile inveeeeeention!" Do not see before working with first graders and/or getting on a plane.
** "How I Saved Roosevelt" is another one you don't want to sing in public - ''"Too cold for the stomach in Washington/I go down to Miami, kill Roosevelt!"''
** And, of course, you do ''not'' want to get caught singing, ''"C'mere and kill a President..."''
** Nor do you want to be caught going ''"Damn you Lincoln, you righteous whoooooooooore!"''
** ''Everybody's got the right to some sunshine/not the sun but maybe one of its beams...''
** The Ballad of Guiteau counts, too. ''Look on the bright side, look on the bright side...''
** ''In the USA you can work your way to the head of the line...''
* EvilIsSexy: "Johnny Booth was a handsome devil."
* GermansLoveDavidHasselhoff: Initially met a much better reception in the UK than the USA.
* NightmareFuel: The end of Lee Harvey Oswald's scene, when all the assassins surround him singing about how much they admire him while he loads his rifle and prepares to shoot Kennedy. The LyricalDissonance and the menacing sound of the melody make it especially creepy.
* OneSceneWonder: Depending on the direction, The Proprietor may pop up throughout the rest of the show, but he's only scripted for the opening scene, leading "Everybody's Got the Right". In the original production, Lee Harvey Oswald was this as well, though ever since the 2004 Broadway revival, it has become common practice to double him with The Balladeer.
* TearJerker: "Something Just Broke", the one truly honest and heartbreaking song in the show, about the everyday aftermath of an assassination.
** Booth's solo in "The Ballad of Booth" qualifies, as well.
** The reprise of "Everybody's Got The Right" was one in the original production.
** Czolgosz's portion of "The Gun Song," where he meditates on all the men who labored in factories or mines and were injured or killed just to make a simple object which in turn will be used to kill ''more'' people.
