A family is at the zoo and they get to the elephants when the daughter notices something odd so she looks at her mom and says, "Mom what's that thing hanging down from the elephant?" She answers, "That's his trunk." "No, in the back," the daughter says. "That's his tail." "No, underneath!" The mother blushes and says, "Oh that's nothing."
The daughter is confused, so she asks her dad. "Dad, what's that thing hanging down under the elephant?" "Oh, that's his penis," the day replies. "Why when I asked Mommy did she say it was nothing?"
