Mario is no longer a plumber, according to his recently updated profile on the Japanese Nintendo page. This comes as no surprise, considering it’s been years since Mario’s really worked his supposed job.

Let’s be clear: This isn’t us calling Mario anything less than a consummate professional. As long as we’ve known him, Mario’s kept busy with a bunch of other things. He’s saved Princess Peach — nay, the entire Mushroom Kingdom — numerous times. He’s a tennis, baseball, soccer and even Olympic champion. Mario’s even done a brief stint in the professional dancing space.
