Pounding the Pud for the Poor

I wish I could say, "only in San Francisco," but sadly, that is not true. But it did begin there. San Francisco held a "masturbate-a-thon" to raise money for some undesignated charity. I wonder. How do donors verify that they got what they paid for? When we do a Crop Walk, we verify that people walked their 10 kilometers. While there is a way to prove that men finished the job, we have to take the women's word for it.
