Biblical Haircut

A preacher's teenage son gets his driving permit and asks his father to borrow the car.

His father says, "You can if you first bring up your grades, study your Bible, and finally get your hair cut." A couple of months go by and the son again asks his father if he can borrow the car. His father says, "Well, son, you brought your grades up, you've been studying your Bible, but you haven't cut your hair yet." His son says, "Yeah, I've been thinking about that. You know Moses had long hair, and Samson had long hair, and even Jesus had long hair." His dad says, "That's right, son. And they walked everywhere they went."
