Portland has a playful article in its December 2007 issue about words or phrases the Maine Bureau of Motor Vehicles (BMV) prohibits from appearing on vanity license plates. According to the Portland piece, there are more than six thousand entries on the "Bleep List," so I'll let your imagination fill them in.
For anyone out there who thinks they're sly enough to slip one passed the Bleep Czars, the BMV also resorts to a mirror test. TIH2 TA3, for example, failed to pass the bleep test after a mirror revealed it to be "eat shit." I hope too many brain cells weren't wasted by that plate's hopeful owner.
