When I was younger and foolish, I agreed to help my boss feel a staffing void for a month and a half, which involved at least 20 hours of extra work. I was on salary, so of course it was unpaid overtime. My boss gave me a bonus of $50. That alone is kind of messed up, but my boss should have given me a raise, because it was the end of the year and that's when raises ought to be given, and instead of giving me a raise they gave me that $50 bonus.

I took the money, but I immediately lost all respect for my boss and stopped caring about that job. It was a good lesson, though. Don't work unpaid overtime, and expect your boss to shaft you, because they can take home the money that ought to be going into your wallet, if you let them.
