As I was registering my car at the DMV, the clerk picked up the next plate from the pile and said "121 QC. That'll be easy to remember." I remarked that the second customer after me would have an even easier one to remember and she paused for a moment before exclaiming "Oh, 123! You want that one?"
I put the plates on today because today I brought my car in for the State Inspection. I needed a bulb in a tail light and the hardly tinted by Arizona standards windshield was pretty dark by Maine standards and needed a special test to make certain it wasn't too dark. I now have a certificate to that effect and can show it every year when I get my car inspected and they won't have to do the special test again.
