Facebook Follies: Sioux Prayer Request for Gulf Oil Spill

One of my Facebook friends posted that she'll be "attending" the "Sioux Prayer Request for Gulf Oil Spill" on Monday, June 21, 2010. That can't be any less effective than BP's oil leak containment box, and undoubtedly will be much less expensive. But if there's expectation that praying's actually going to help, why wait a month?
