A man wearing a balaclava over his head goes into a bank, aiming to rob it.
The robber goes up to one of the cashiers, pulls out a gun, and demands that they hand over all of their money.
Once he is given the money, he turns to a customer and asks him, “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 to him and asked the man, “Did you see me rob this bank?”
The man replied, “No sir, I didn’t, but my wife did!”
