A little boy who prayed for a bicycle had an even more startling
surprise instead -- a baby sister.  That night he had a talk with God
about His delivery service.  "I got a sister instead of a bike," he
explained to God.  "Maybe some other kid wanted a sister and got my
bike.  Is there any chance we can keep the girl and get me a bike, too?"
