A Quaker was one day walking on a country road. He was suddenly met by a highwayman pointing a pistol. The robber exclaimed, "Your money or your life!"
"My friend," said the Quaker, "I cannot deliver my money, for I should be helping thee in evildoing. However, exchange is lawful and I will give thee my purse for the pistol." The robber agreed. On receiving the purse, the Quaker at once held the pistol at the robbers head and said, "Now, friend, give me back my purse back or the weapon may go off."
"Fire," said the robber. "There is no powder in the pistol!"
