Well...there's Monty Python's John Gambolputty. https://www.youtube.com/watch?v=UDPqB9i1ScY https://www.youtube.com/watch?v=UDPqB9i1ScY While a comical exaggeration, there simply isn't a hard limit - just somebody drawing the line and saying "640 kB should be enough for anybody." As for "ridiculous" - having many names is apparently a nobility custom, even if most people don't insist on using the full name in everyday matters: https://en.wikipedia.org/wiki/Karel_Schwarzenberg https://en.wikipedia.org/wiki/Karel_Schwarzenberg is also Karl Johannes Nepomuk Josef Norbert Friedrich Antonius Wratislaw Menas Fürst zu Schwarzenberg and Karel Jan Nepomuk Josef Norbert Bedřich Antonín Vratislav Menas kníže ze Schwarzenbergu (oh look, several non-equivalent but canonical names!)
