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."
