If I was a rich man

In Spain they are drawing for the world's biggest lottery. 3.2 billion dollars. That would put you in the top 400 richest people in the world, for a meagre outlay of $279.

If I had that kind of money, and was forced to spend it on myself, I would build a sweet as mansion, buy an awesome outfit, and enact vigilante justice.
I guess I just really want to be Batman.

But actually, I would hope that whoever does win it donates a substantial portion to charity. Greg Mankiw solicits some good advice on how to do that. Apparently one of the better charities out there is Deworm the World. Were I in a position to give advice, I would have advised not to name a charitable organisation directly after the slightly nausea-inducing health issue you want to remedy. Still, at least you aren't unsure of their purpose. And if you have some spare change, go ahead and donate.
