You don't think arguing is fun???? That's why we have the China Shop.

There's difference between measuring with something you know is off and correcting for it: "My speedometer always reads 5mph fast"
and something you believe is correct and isn't "But Officer, I had it NAILED at 55mph on my speedometer, not 65".

Can't go swimming. It's nasty, cold and raining. Therefore, arguing is a valid alternative source of fun!
