The Romans may be known for many things, but humor isn't one of them. As usual, this interpretation relies on a prima facie reading of Jesus as a man with no political ambitions whatsoever. That is nonsense. All criminals sentenced to execution received a titulus so that everyone know the crime for which they were being punished and thus be deterred from taking part in similar activity. That the wording on Jesus's titulus was likely genuine is demonstrated by Joseph A. Fitzmeyer, who notes that "if [the titulus] were invented by Christians, they would have used Christos, for early Christians would scarcely have called their Lord 'King of the Jews'."[..] the notion that a no-name Jewish peasant would have received a personal audience with the Roman governor, Pontius Pilate, who had probably signed a dozen execution orders that day alone, is so outlandish that it cannot be taken seriously.
