Not sure why Christopher Nolan doesn't think the "Nobody" pun doesn't translate to modern dialogue. The Odyssey's "Nobody" pun might be nearly 3,000 years old yet remains one of the most famous literary tricks in human history. It holds up today because it is simultaneously a simple joke, linguistic genius, and adds to Odyssyeus's hubris.
There's even another layer to this trick. Odysseus knows he can't out muscle this guy. By stripping his name and becoming "Nobody", Odysseus proves that identity and strength are meaningless without intellect.
After defeating the Cyclops, Odysseus (safe on his ship) let's his ego gets the best of him. He can't stand even his "Nobody" alter ego getting the credit, so he screams his real name back at the Cyclops to let him know who really did this to him.
And of course, now that the cyclops knows it was really Odysseus, prays to Poseidon using his real name. Which in the poem, catches Odysseus a 10 year prison sentence out at sea.
The "Nobody" joke is insanely multilayered and the real punchline is Odysseus can't stand Nobody taking credit for his exploits.
