A man runs into a bank, pulls out a gun and robs the teller. He then turns the gun on the on the first man standing in the tellers line and asks, "Did you see me rob this bank?"

The man stammered, "Yes."

Bang!  The robber shoots him.

He then turns the gun on the married couple next in line, points the gun at the husband and demands, "Did you see me rob this bank?" The husband quickly responds, "No....but my wife did!"
