Another popular one is the 'Grandma/Grandpa scam', where someone phones and says "Hi Grandma/Grandpa, it's me!", and then waits for the answering person to guess a name. Of course, the scammer then runs with that name, saying they're in trouble, please send money.... It relies on the grandparents having infrequent contact with the the grown grandkids. My mother, who was sleeping when the phone rang, actually got hooked with one such call, but, unbeknownst to the scammer ("I went out and got busted for drunk driving and i'm in jail please send money to bail me out"), my mother lives downstairs from us and her then-16 (and uninterested in driving) granddaughter. The response the scammer got was "No, I'll come get you" and a flurry of phone calls then followed, to my wife's work, my work, and my daughter's school. I can imagine the puzzled look on the face of my daughter's teacher (and the 'what'd i do?' look on my daughter's face) as the teacher is on the phone saying "No, she's right here in front of me..." My response when I got the call at work was instant: (Admiral Ackbar voice:) "It's a scam!!!!" My daughter was teased about being a jailbird for awhile after that.
