One day, 2 young children, a boy and a girl, too young to know about sex, were taking a bath together. They both look down at the same time and say:
"Hey, what's that?"
So the both go see they're parents, and the father says to the boy:
"That's your Limo, you park it in a girls garage!"
The mother tells the girl:
"That's your Garage, never let a boy park his car in it."
So the next day, they take a bath together. The little girl runs to her parents screaming and covered in blood. The parents asked what happened, and the little girl replies:
"A boy tried to park his Limo in my Garage, so I popped his back tires!"
