Confidence man and Confederate in Cahoots with a Co-Conspirator the Clairvoyant Criminal. (And Carnac)
Those of you old enough to remember Johnny Carson's "Carnac the Magnificent" might understand this photo. The master talk show host conspired with his straight man Jolly Ed R.I.P to produce a skit which never got tired. Here, Some poor woman having turned over her life savings for one brief message from her dearly departed has no idea the news from heaven is actually coming from the proverbial man behind the curtain. Slick! Known as "Billet Reading" the message could read "withdraw funds from bank and give to man with moustache.
As for Carnac, I would link to them all if I could, but you'll find the good ones.
