Take ONLY ONE

It was lunchtime at the Jewish nursery school and all the children were
lined up by the teachers. Then, as usual, they were led into the canteen.
Little Moshe quickly noticed that at one end of the dining table was a large
pile of apples with the message, "Take ONLY ONE apple each, God is
watching."  At the other end he noticed was a large pile of kosher chocolate
chip cookies.
Moshe then whispered to his friend Sarah, "We can take all the cookies we
want. God is watching the apples."
