Austrailian license plates go two numbers, two letters, two numbers. And my friend there was deathly afraid of getting his plate to say "HE20IN" Because he said the cops would pull him over all the time and slice up his sets and flip through his stuff looking for drugs My own mediocre attempt at humor has been highly amusing to myself.. You canget a custom plate there, as long as no one else has it of course, in that format XXNNXX. I remember we spent all night coming up with funny alterations.
