My mother received a call today from someone with a heavy accent saying that his name was Detective John Dolby from the FBI. He was contacted by the Better Business Bureau who was contacted by the 'American Money Mart' (I think that's what he called it) to assist them in delivering a large sum of money. He said to call him back later to let him know when someone will be home.
For the hell of it, I called the FBI and they never heard of him.
The phone number was (Jamaica of course) 876-417-9907
