A man walked into a bank, got in line and when it was his turn he pulled out a gun and robs the bank.
But 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, Well, yes!
The bank robber raises his gun, points it at his head and shoots 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.
