Passing the Pie

Little Johnny was eager to help when his parents entertained several
dinner guests.

When the dinner was nearly over, Little Johnny went to the kitchen and
proudly carried in the first piece of apple pie, giving it to his father
who passed it to a guest.

Little Johnny came in with a second piece of pie and gave it to his
father, who again gave it to a guest.

This was too much for Little Johnny, who said, "It's no use, Dad. The
pieces are all the same size."
