A man walks in a bank, gets in line and when it is his turn he pulls out a gun and robs the bank! Just to make sure he leaves no witnesses, he turns around and asks the next customer in line, "Did you see me rob this bank?" The customer replies, "Yes!" The bank robber raises his gun, points it to the customer's head and BANG !!!, shoots him in the head and kills him! He quickly moves to the next customer in line and says to the man,"Did you see me rob this bank?"The man calmly responds ... "No, but my wife did."
