What's the craziest thing you've ever done.....for a cause?

Whether you wanted to or not, chances are you've seen a clip of some fame seeking lunatic eating raw bull's balls or climbing through a pit of cockroaches on reality television.  (Aren't you glad I evoked that visual for ya?)  There seems to be no end to what people will do for money, but what about money for charity?  It seems reality shows have gotten on the do-good bandwagon, donating proceeds from this challenge or that to a charity of the winner's choice.  Kudos to that, if we can inspire people to get up and do.......something......to help others, I think that's awesome.You know what else is awesome (not to mention completely insane), Burroughs Annual Freezin' for a Reason.
Apparently, every year the crazies gather to run into the Long Island Sound during the chilly month of February to raise money for the Burroughs Community Center in Bridgeport CT.  Really people?  Actually, I would totally pay to see this, so I did, and you can too.  Make a donation to Burroughs here.  
So what's the craziest thing you've ever done for a good cause?  Run a marathon (yes, I consider marathon running a completely insane undertaking)?  Eat bugs?  Jump into the Hudson River (gross, right)?  Keep up the good work crazies, you're making a world of difference!
