Have you ever received a windfall?

I'm here in Mexico City. A month ago I was walking along a street, looked down, and there was a 100 peso bill (equivalent of $8). I haven't spent it. It's sitting on my tv because the last time I found money on the ground (strangely, 2-50 peso bills also in this city), I spent it and it turned out to be bad money. So in lieu of not wanting to bring me bad luck again, I'll probably end up giving it to someone as a tip.
