A couple took their young son to the circus. During the show, the father got up to buy some popcorn. Just then, Jumbo the elephant came into the ring. The boy looked at the elephant and asked his mother; " What is that thing hanging between the elephants legs?"
"Oh," she replied, "that's his tail."
"No," the boy said, "in front of that."
"Oh, my," the mother replied, "um, er, that's nothing, honey."
The boy, realizing that further prying was useless, sat back to watch the show. The father returned with the popcorn, and the mother left to use the restroom. Trying again, the boy asked his father; "What's that thing between the big elephants legs?"
To which the father replied, "That's his penis."
"Then why did mommy say it was nothing?" the boy asked.
"Son," replied the father, "I've spoiled that woman."
