There exists one piece of in-game evidence in favor of the widespread Internet joke that Yoshi does not pay his taxes: in Fortune Street, Yoshi is the only one out of 26 characters that requests to be exempt from paying taxes when the player builds a new tax office.

An extremely detailed 2018 Waluigi render shows that the "Γ" emblem on his hat is a sticker, as a corner is peeling off. This suggests that unlike Mario, Luigi and Wario, who have tailored caps, Waluigi was only able to afford a cap with a blank emblem that he customized himself.

Human DNA has an information storage capacity that very neatly fits the size of a GameCube game. Thus, it would be possible with gene editing technology to store a copy of e.g. Super Mario Sunshine inside the human genome. Details in image.

In light of the recent news that the Tokyo 2020 Olympics are being postponed until 2021, Mario & Sonic at the Olympic Games Tokyo 2020 now has the unique distinction of being based on an alternate version of a real-life event that will not happen in the form depicted in the game.

Super Mario Galaxy contains zones called "NoSleepAreas", placed wherever it would be inappropriate for Mario to fall asleep when idling, such as in boss battles. However, no such zone exists in front of Luigi's prison, allowing Mario to sleep while Luigi is pleading him for help.

In 1994, Nintendo made a public event at a Dutch airport where 10,000 counterfeit Game Boy games they confiscated in the Netherlands were ran over by a steamroller, to send a message to counterfeiters. An actor in a Mario costume was overseeing the operation.

According to a 2017 study by a team of Canadian neuropsychologists, playing Super Mario 64 increases grey matter in the brains of older adults, potentially being able to combat dementia and other neurological disorders.

The 1995 Japanese guide for Mario's Super Picross contains a short comic built on the same premise as the American Mario cartoons - that Mario and Luigi have a plumbing business in Brooklyn - with the difference that Princess Peach is also an employee at their company.

I have recently received inquiries about my personal collection of Mario merchandise. Below is a photo of all Mario merchandise I own. It is a single officially licensed 2011 keychain of a Wallop enemy from Super Mario 3D Land, which is of great sentimental value to me.

In Super Mario Galaxy 2, Peach periodically sends letters to Mario. Each of these has its own text, but that text actually overwrites preexisting nonsense text included in the letter's internal layout file. Here is what the letters look like if the placeholder text is left in.

The Piranha Plant fighter in Super Smash Bros. Ultimate has legs that appear briefly during certain animations (left). The legs are never completely extended out of the pot. On the right is the model extracted from the game's files, showing the full length of the legs.

Today, the first ever photograph of a black hole was released to the astrophysical community (right). While the depiction of a black hole made in Super Mario Galaxy (left) 12 years ago does not entirely match up with the real black hole, the similarity is nevertheless remarkable.

An official render of Toadette for Super Mario Maker 2 contains the most realistic depiction of a piece of Nintendo hardware in artwork for a first-party Nintendo game to date: a Joy-Con that is modeled in such detail that it even includes all the legally mandated labeling.

The Internet contains many outlandish Mario-related images, of which most are presumed to not be official material. I have compiled a set of images that I have seen online commenters consistently assume to be edited or fan-made, but which are in fact completely official.

In Super Mario Odyssey, Mario is able to fall asleep off edges of platforms, appearing to float. However, in Super Mario 64, code exists that checks whether there is ground behind Mario first. Thus, in a game 21 years older, sleeping is implemented in a more sophisticated manner.

Despite looking much more detailed, the model for the coins in Super Mario Odyssey is actually 65% simpler than the one used in Super Mario Galaxy, due to taking advantage of modern rendering techniques. Details in image.

In Super Mario Odyssey, the game does not handle Mario's legs being on two different slopes correctly, with him appearing to stand halfway in mid-air (left). In contrast, Super Mario Sunshine, released 15 years earlier, has code that handles each leg's incline separately (right).
