Yeah, I got a couple of the "help me I am a poor Nigerian prince with tons of cash that I want to share with you."
I worked in the banking field, and we had some really great ones come through. Fortunately I was able to convince several people they were not really lottery winners, random inheritance receivers, saving people from other countries, etc...
One that sticks out in my mind was actually a very good one. Some one called an elderly W. and said, "Hey this is your favorite grandson." When she named him he said, "Yeah it's me." Then railed off about how he went to Mexico for a trip, was arrested and needed money for bail. She called us to wire the money to him. I told her to call her grandson and tried to get a hold of him first. After a little convincing she did. Grandson was fine and at home.
Smart of him. He let her decide who he sounded like, and then went on with his story.
