One day 12-year-old Jake is given a drive in his friend's family Ferrari. He thinks it's so cool that he races home to his Dad and yells, "Daddy! Daddy! Can I PLEASE have a Ferrari? PLEASE?!"
The father sighs. "Jake - does your dick reach your butt?"
Jake pokes around downstairs and finally says reignedly, "Um, no".
"OK. Well come back and discuss this when your dick reaches your butt."
Every year for five years, Jake comes back and asks for his Ferrari, and every year they have the exact same conversation.
Finally, in the sixth year, Jake comes running down the hall yelling "Dad! Dad! Could I have my Ferrari now? See? My dick reaches my butt!"
"Good. Go fuck yourself!"
