Help a man lose his hair!!

Over on Scienceblogs, Ethan Siegel is trying to do some good in the world, and I think you should help him out. He's encouraging people to volunteer, donate, and be generally awesome people. The incentive? If he gets 100 people to do a new act of awesome charity work, he'll shave his head. And for a dude with long hair, that's a pretty big deal. I decided to donate my locks as well, to help his cause. I'll be cutting my hair in a little over a week I believe, and will post some photos of the event. So, help make my hair donation more worthwhile by donating some of your time/money/energy to helping others!!! (And current things to you do not count; it must be a new act.)
