* DemonicSpiders: The green fireballs, which spawned not from the pipes, but ''directly on your current floor''.
* EarWorm: The opening snippet of "Eine Kleine Nachtmusik," a classic [[Creator/WolfgangAmadeusMozart Mozart]] song.
* HilariousInHindsight: The [[http://www.youtube.com/watch?v=AnU-2HRJNO4 commercial]] for "Atari" ''Mario Bros.''

** That having been said, Nintendo still shows this game a lot of love, having remade it multiple times (most notably as part of the ''[[VideoGameRemake Super Mario Advance]]'' series and ''VideoGame/MarioAndLuigiSuperstarSaga'') and even making it a stage in ''VideoGame/SuperSmashBros Brawl''.
