Apropos of nothing, here's my personal headcanon in regards to Mario and Luigi's surname.

Now, it's been generally announced and accepted that the brothers' last name is "Mario," shackling them with the somewhat awkward full names of "Mario Mario" and "Luigi Mario." My take on this is that the family's original last name was "Marianetti" (likely coming from the more common "Marinetti"). This name was changed to "Marionetti" when the boys' grandmother came over from Italy. (A common occurrence in record keeping at immigration at the time. Someone probably had bad handwriting and smudged a pencil stroke somewhere. It happened in my family for sure).

In Brooklyn, their father went by the last name "Marionetti," which ended up shortened to just "Mario," as oftentimes he would be addressed by his surname only. (Think, "Hey, Mario! Get over here!" as opposed to "Hey, Marionetti! Get over here!")

So, the boys are born and get their names. (Their father's middle name was Mario, and so our Mario, being the oldest, inherits his father's middle name as his first name. Luigi's name maybe comes from the middle name of some uncle who is long out of the picture).

So we have "Mario Marionetti" and "Luigi Marionetti." Which, their surname being a mouthful, gets shortened to "Mario" more often than not, just like their father. And thus we end up with "Mario Mario" and "Luigi Mario," culminating in the "Mario Brothers."
