"Did you hear the one about the guy who was too poor to get personalized plates so he changed his name to J3L2404?"
I am assuming that J3L2404 was the license plate number he was given by the BMV. He couldn't afford to get a personalized plate with his name so he changed his name to J3L2404. So his name would match his plate number, therefore it would be a "personalized plate". Kind of hard to explain, hope that makes sense..lol.
