I have a fixation with vanity license plates. I try to evaluate the character of the driver based on the license plate. If it looks like a well thought out message or nickname, the driver is more or less decent. If the license plate is merely a way to tell us what model the car is (HUMMRRR, as I once saw), obviously the driver is a douchebag.
Today, I saw the queen mother of all douchebag vanity plates. It was on a newish Mustang, and the plate said:
Now, I'm guessing the owner meant to tell the world that this was "Mom's Mustang (Mom's 'Stang)". But, as noted, the appropriate way to say that would be MOMSTANG. MOMSTANG is Mom's Mustang. MOMTANG, on the other hand, is something very different. It may as well have said Mom's Box.
Think about what you want to put on a vanity plate, or some smartass such as myself will be right there behind you, taking notes.
