A visiting minister offered up a prayer during Sunday morning service.
"Dear Lord," he began with arms extended and a rapturous look on his upturned face, "without you we are but dust..."
He would have continued, but at that moment, one very attentive little girl leaned over to her mother and asked quite audibly, "Mommy, WHAT is butt dust?"
Church was pretty much over at that point.
(Not sure if this is a true story... but it sure made me laugh hard.)
