the smoking gun has some funny files of people offended by personalized license plates - florida and wisconsin in particular

i especially liked the florida plate "FUCT 24 7" (with the complainer dotting her i's with little hearts - *gag!*)

the wisconsin plate "WMWNMNW" is also particularly brilliant because of the difficulty it would cause a cop in calling it in...a subsequent comment on fark was "For the bisexual among us, WMNNMN would be appropriate (and difficult to read)."

of course, if ya can't get a vanity plate for your car, you could just make one at the acme.com licensemaker...
