George Washington... a psychic, too?
Show your friend a dollar bill and tell her to look at the serial number and to concentrate on just one of the numbers.
Tell her that George Washington wasn't just the first President of the United States, but he was also a psychic!
Ask her what the number was and after she tells you, you show her your prediction - one that was already written on the dollar bill before you began! Carry this one in your wallet. It's a good one to do anytime!
