A friend of my dad's was really good at finding gaps in the rule books of dirt track speedway. Like, for instance, it might specify you could only have a radiator of a certain capacity in the car to cool the engine, but it didn't specify where it had to be mounted. If you can find somewhere with less mud being thrown at it or better air flow, then you've got a competitive advantage. Eventually some Nascar teams became aware of him. He told them his time was worth a lot of money. "Money's not a problem!" "If you're serious you'll send me a blank check." Two teams sent him checks. He filled in some unnamed amount, waited to see if it cashed and then ripped up the other one. He spent a few months in the States, came back, and bought himself one of the biggest houses in town. Sometimes chutzpah pays off. :)
