Buy a ticket to the Match Against Poverty

A friendly soccer match will be held in Hamburg on 13 December, with 2/3 of the proceeds going to the UN's food crisis in East Africa. It's entirely likely that you: a) don't care about soccer, b) don't live anywhere near Germany, c) can't afford to buy tickets, d) are generally reluctant to leave the house, or e) meet some combination of the above characteristics. But if you know someone who'd be interested in going, it's worth mentioning http://www.beta.undp.org/undp/en/home/ourwork/goodwillambassadors/match_against_poverty.html.

Effort involved: arranging a trip to a soccer match could be quite a bit of effort, depending on where you are.  But if you're a fan this may feel more like play than like work.
