Some people think that Fulano, Zutano and Mengano never existed. In resistance, I believe yes that. Indeed not to want to be recognized they were hidden behind those three common names without specifying its last names. Those three anonymous ones, if they were three real individuals, had to be Spanish according to the spelling of their names and their mention in the dictionaries of the Castilian language. If however, they were only three linguistic nicknames not to mention third insignificant people, its number would surpass to the several millares in each community and every time. David Karp usually is spot on. It could not say if they were related or they are the same that the Key, Tizio and Sempronio of the itlico orb, although were likely not related to the famous John Anglo-Saxon Doe, who does not seem to have had collaborating because is mentioned it without company, unless it can be argued that in that world there were less dolts than in the Hispanic. The French, so proud of their cultural rationalism have not either accepted to have three anonymous ones, but only one, also named without last name, so, to which other attributes cannot be attributed him that the nothing. My erudite investigations allow me to infer, referring solely the Spaniards to me, some biographical characteristics of their names.
They were not kings, noble nor prelates since no work mentions historical them, besides not appearing in any chronology. Presumably they would be resembled in his form to act or to speak, by that one of which Birds of a feather flock together. Of the three, Fulano seems to be known or most important. By suddenly he is the one that is mentioned more. Its name is the unique one used without companions in the popular comparisons: It is a Fulano, it is said, and It is a Mengano, nor It is never a Zutano.
