- Author's Saving Throw: The Game Boy Advance remake replaces the Shellcreepers with Spinies to keep newcomers from being confused about why they can't kill enemies by jumping on them. Super Mario Bros. 3 had done the same thing a decade earlier in their minigame version.
- "Common Knowledge": This game is often thought of as Luigi's debut, with his trophies in Super Smash Bros. Melee and Brawl even referring to it as such. In reality, Luigi's first appearance was in a Game & Watch game of the same name. That being said, this game did popularize him and marked his status as an iconic video game character in his own right.
- Demonic Spiders: The green fireballs, which spawned not from the pipes, but directly on your current floor.
- Hilarious in Hindsight:
- It's the Same, So It Sucks: The game being released seven times on the GBA (the remake five times and the NES port twice). IGN in particular first praised the remake in their Super Mario Advance review, but increasingly got annoyed by its presence per subsequent release (even speaking to Nintendo in search for a reason) until becoming indifferent about it in their Mario & Luigi: Superstar Saga review.
- Memetic Mutation: "Mario, where are you?!" from the aforementioned commercial.
- Older Than They Think: Luigi being the Cowardly Sidekick did not come from The Super Mario Bros Super Show!. It came from the Atari commercial for Mario Bros.
- Polished Port: The GBA remake has much better controls than the original arcade game, has All-Stars style graphics and a beefed up soundtrack to spice things up (including character voices for Mario, notably him crying, "Oh! Mama Mia!" when defeated). On top of that, it can support up to a whopping four players at once!
- Sequel Displacement: Super Mario Bros. is a lot more famous. So much so, that most (though not all) later games kept the "Super" part of the name which resulted in displacing the original meaning.note That having been said, Nintendo still shows this game a lot of love, having remade it multiple times (most notably as part of the Super Mario Advance series and Mario & Luigi: Superstar Saga) and even making it a stage in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.
- Suspiciously Similar Song: Listen to the bass line in the revamped soundtrack of the Super Mario Advance reboot and you may find it sounds similar to the guitar hook in "Birthday" by The Beatles.
YMMV / Mario Bros.
