Nobody knows
In Homer's "The Odyssey," the main character Odysseus is battling a cyclops. When the stupid cyclops asks Odysseus' name, Odysseus lies and says his name is "nobody." The cyclops is ignorant of the meaning of that word, so when Odysseus creeps up and stabs the cyclops in the eyeball, the cyclops shrieks for help from his partnas, saying "Help! Nobody is killing me!" The cyclops' pals assume it's a joke, so they don't help him, and Odysseus gets away.
Nobody else knows how I got my name, so please don't tell nobody, cuz it's just nobody's business.
