The children were lined up in the cafeteria of a Catholic elementary school for lunch. At the head of the table was a large pile of apples. The nun made a note, and posted on the apple tray: "Take only ONE. God is watching."

Moving further along the lunch line, at the other end of the table was a large pile of chocolate chip cookies. A child had written a note, "Take all you want. God is watching the apples."
