A teenage boy just passed his driving test and inquired of his father as to when they could discuss his use of the car.
The father said he'd make a deal with his son. "You bring your grades up from a C to a B average, study your Bible and get your hair cut. Then we will talk about use of the car." The boy thought about it, decided he'd settle for the offer and they agreed on it.
After about 6 weeks, his father said, 'Son, you've brought up your graces and I've observed that you have been studying your Bible, but I'm disappointed that you haven't had your hair cut.
The boy said, You know, dad, I've been thinking about that and I've noticed in my studies, 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.
Dad's reply, ' Did you also notice that they all walked everywhere they went??"
