"Spotted this one near Lichfield in Staffordshire. Not sure what 51 NN means other than: I am a cunt, who drives a cunt car so therefore I will take up two spaces with my lousy parking. What a cunt."
We think the numbers help explain what the plate stands for “51 nanometer nob”. OK, we need to be a bit creative with the spelling but that’s probably how their pea-sized brain spells it anyway. All other suggestions are welcome.
