Once, a little girl was walking in the park with her mother.
"Why do mommies know everything?"
she asked her mother.
"Because we have to pass a test before we can become mommies."
her mother replied.
After taking a few minutes to ponder this, the girl finally exclaimed:
"Ohhh! I get it now! So the one's that don't pass the test become daddies, right?"
saw it on an email a long time ago. :)
