I was paid $50/hour for quite some time to do "marketing consulting" for a company started by a douchebag studying at Harvard. It was vaguely interesting work, and I over delivered on every expectation, but grew tired of his increasingly demanding explanations (pages long at times) of why I did what I did and who the market was. Those two questions were asked of me obsessively.

Eventually, after I told him I was sick of doing write ups that were completely unnecessary, he admitted he was taking a marketing class at Harvard. I was unknowingly doing all of his exercises, and he would turn my write ups in to the Professor. Apparently he got an A.
