On the autobahn today there was a porsche behind me. the driver was a nice one for the usual "german porsche driver" I know...
After a while he switched lanes and drove away... only then I saw the license plate... I had a little laugh... it said: "BAD - IQ - 1".
And another licence plate already gone was from my now home town " HH - BE - 1337 " still have to find the person having that on his or her car and shake them hands =)
