A family goes to the circus - mom, dad, and their son. The elephant act comes out & the son asks his mom, "Mom, what's that long thing hanging down on the elephant?" His mom says "That's his trunk." "No, I mean the long thing in the back." "That's his tail." "No, the other long thing hanging down in the back, between his legs." Mom says "Uh, that's nothing. I'm going to go get us some sodas." So after she leaves, the kid turns to his dad & says "Dad, what's that long thing hanging down on the elephant? Not his trunk, not his tail, the other long thing hanging down between his legs." His dad says "Oh. Well, that's the elephant's penis." The son says "So how come when I asked Mom what it was, she said it was nothing?" Dad put his arm around his boy & said "Son, I have spoiled that woman."
