A teenage boy just passed his driving test and asked his father if he could use the family car.
His father anticipated this question and replied, “I’ll make you a deal. If you bring your grades up to a B average, study your Bible a little, and get your hair cut, you can use the car.”
The boy thought about it for a moment and agreed to take the offer.
About six weeks later his father said, “Son, you’ve brought your grades up, you’ve been studying the Bible, but I’m disappointed you haven’t cut your hair.”
The boy answered, “You know, Dad, I’ve been thinking about that. I noticed the Bible says that Samson had long hair, John the Baptist had long hair, Moses had long hair … and there’s even strong evidence that Jesus had long hair.”
So his father replied, “Did you also notice they all walked everywhere they went?”
