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 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."
