Received this call today (and yesterday) and it was someone calling for a donation for the police rodeo... and we told them to send us something by mail and he responded that he needs a commitment over the phone. He kept saying he wanted us to commit over the phone and we said send it via mail and we'll respond that way. He then said have a good day and hung up... it's a scam.
Presumably one of the world's leading purveyors of snake oil and other miracle products. He now is on my block list. If one of these lower forms of life ever gets through to me, I shall tell him that I learned a special prayer from an Indian guru that provides me with a lifetime supply of whatever he is selling.
