At church one Sunday, a teenager made a contribution to the collection plate by dropping in a coin from him pocket.
As he passed the plate along, someone behind him tapped him on the shoulder and handed him a $20 bill. Impressed by the person's generosity, the teenager added the $20 to the collection plate.
But then he received another tap on his shoulder and heard a whisper, "Son, that was your $20. It fell out of your pocket."
