Little Johnny and two of his friends were sitting on a front porch one day after school. Billy looked down the street and saw a bright red Corvette. "Some day I'm gonna be a lawyer so I can buy me one of those Corvettes," he said.
Robbie looked over at the driveway next to the Corvette and saw a brand new Ferrari. "I'm gonna be a doctor," he said, "so I can get me a fast Ferrari."
Little Johnny looked over at the other two and said, "I'm gonna learn how to suck dick when I grow up." The other two boys looked at each other in disbelief, not believing what they'd heard.
Little Johnny continued, "That's what my sister does, and she owns both of those cars."
