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 shot him in the temple, killing him instantly.

He then turned to a middle-aged couple standing there and asked the man, 'Did you see me rob this bank?' The man replied, 'No sir, I didn't, but my wife did.'
