What are some unusual ways by which you have made money?

I was once walking by the street and a man stopped me to propose a 'tea tasting gig' to earn a quick 100 Rupees. I was taken to a shop and asked to taste and smell some tea samples. All I had to do then was write my feedback on a piece of paper. Best part was that it was an anonymous feedback. Then I got my 100 Rupees(around 2 US Dollars then) which I used to treat myself with a Pizza. That is one weird way I have made some money. I would like to hear your stories too where you made money in some weird or unusual way.
