"Mommy, tomorrow I have an oral exam, and one question the teacher will ask me is 'who made you?' What should I say?" asked John.
"God made you, dear," replied his mother.
The next day, when the question came up, poor John forgot what his mother had said. So, he explained, "Teacher, until yesterday I was sure it was my Daddy who made me, but then Mommy said it was someone else... and I can't remember the guy's name."
