A colleague and I demo'd something really neat we'd made in our spare time to the execs at the tech company we worked at, as a potential investment. Two days later the network admin of the company stopped by my desk and whispered in my ear, "They're looking at your employment contracts. Whatever you showed them, they are trying to figure out if they can take it for free." (I guess he was reading all their emails...) Bad news for them: they'd been in such a bind to hire me originally that I'd taken a pen and scribbled out a large chunk of my employment contract before we signed it. I'd never have thought to try it, but someone with bigger balls than me had done it the day before on theirs and told me about it.
