On a related note, when we had restored our old VW Bug and put Herbie stripes on it, I tried to get vanity plates that read "LOVEBUG", but the state's system deemed it vulgar/obscene/whatever, so we put a plain plate on it.

In a cruel twist of irony, a couple years ago I was passed by another Xterra with a vanity plate on it with the letters "WTF". Go figure.
