A man with a gun goes into a bank and demands their money. Once he is given the money, he turns to a customer and asks: 'Did you see me rob this bank?'
The man replied: 'Yes sir, I did.'
The robber then shots him in the head, killing him instantly.
He then turned to a couple standing next and asked the man: 'Did you see me rob this bank?'
The man replied: 'No sir, I didn't, but my wife did!'
