Saw a picture of a Volkswagen Rabbit with the license plate “FXLK12”...
She stopped at a redlight and I asked her {young, attractive woman} what it meant and she smiled and said, "Do I look like I give a f---?"
I know it was a little rank, but both my son and I laughed our butts off.
I’m ashamed to admit I got that one immediately.
The best vanity plate I’ve seen on a VW Bug was “FEATURE”. Of course you kinda have to be a little geeky to get it.
