A six year old kid walks in to his parents' room. When he opened the door, he stopped in shock when he saw his father pumping away at his mom.
The kid says, "Hey, Dad, what are you doing?"
The father was surprised to hear his kid's voice from behind so he stopped pumping, but didn't pull his rod out. Without turning his head, he answered.... "Ah, er..... Nothin' son, ah...... I was just.... I was just parkin my car...... inside your mom's garage."
"Really?" the boy replies.
"Ah,......yeah."
"Well," said the kid, "you'd have to push more pedal, Dad, because the rear wheels aren't in yet."
