I recall a story about a person who got vanity plates and it asked for their top three choices. Having only two they wrote “none” under the third choice. Of course, they wound up with plates reading “NONE” but decided to go with it.
Soon after they were receiving notices of parking tickets and other violations from all over the place as every infraction made by cars with no plates where an officer had written “none” on the ticket suddenly found a match in the database.
I have no idea if this story is actually true. (Actually just looked it up. According to Snopes it’s not only true but has happened more than once with other variations of the plate.)
