A curious little boy asks his mom what his younger sister has between the legs; the young mother does not know how to explain to the boy, so she says: "It's like the Garage."
The boy then asks: "What is mine called?" "It's called the Car." the mother replies. A few days later, the phone rings while the parents are "busy" in the bedroom; the little boy answers it. It's his dad's friend: "Is your father home? Could I speak to him?" "Yes, but he's busy", the boy replies.
"What's he doing? I wanna talk to him..." "Wait, let me check." The boy looks through the bedroom keyhole; then comes back and says: "He's putting the Car in the Garage "Ok, I'll call back." A short while later, the man calls back:
"Can I talk to your dad now?" "He's still busy." "What? What's he doing? How long does it take him to put the car in the garage anyway?" "Wait, let me check." The boy, again, looks through the bedroom keyhole, comes back and has this to tell his dad's friend: "He's still trying to put the Car in the Garage; he keeps moving the Car back and forth.
He seems to have problem putting the rear wheels of the Car into the Garage."
