A couple of great quotes.

One by Douglas Bader (WW2 Fighter Pilot)
"Rules are for the guidance of wise men & the obedience of fools"

Unknown
"May the best cheat win"

Another funny little story I heard of Harry Firth (the king of bending rules to breaking point) from the 70's after he left Ford & went to HDT. He put in a complaint about illegal parts being used on the falcons. When he was questioned about how he would know about those parts. He replied I put them on!"

Also in the days of the Cortina GT, to qualify the cars to be production cars all parts had to be listed in the factory parts catalogue & available in the local dealer. So Harry would re write the Ford parts catalogue & make a few available to certain people.
A couple of days before the race a crate would arrive at the local ford dealers that no one but Harry was allowed to open. If the scrutineers questioned the parts used on his car, he would pull out his special parts catalogue & then take them down to the dealer & crack open the crate showing that the parts were available at the Ford dealer. Not cheating but cutting it very close.
