Saying that it is a "once in a lifetime" opportunity and that you have been selected to receive an 8,000 grant from the US Government. They did not ask for a person by name - and this is a multi-person household. In this area, someone had followed through with this call and ended up losing money. I told them it was a scam - the woman then said it was not a scam it was "being used for training purposes" (???) and I replied that I wanted my number taken off of the call list.
