A teenage boy had just passed his driving test and, as any teenager would, asked his father when they could discuss his use of the car.
His father said he'd make a deal: 'You bring your grades up from a C to a B average, study your Bible a little, and get your hair cut. Then we'll talk about the car.'
They agreed on it.
After about six weeks his father said, 'Son, you've brought your grades up and I've observed that you have been studying your Bible, but I'm disappointed 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 of the Bible 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.'
His father replied, 'Did you also notice they all walked everywhere they went?'
