Nascar cheatin' in the Hemi era.

I always got a kick out of the "creative interpretation" of the rules in all forms of motor racing.
I remember an article in an old Car Craft magazine about, I believe, a NHRA Stock or Super Stock racer. The rules at the time said you had to have a spare wheel and tire in the trunk...but the rule didn't say the tire had to be inflated with air. The car owner filled the spare tire full of water under pressure in order to put a little more weight over the rear wheels for better traction. He got away with it until a tech inspector with a little spare time decided to hit the Schrader valve to see if the spare tire was inflated - and ended up getting a shower!
