How Short Dad ?

A teen just got his drivers permit. He ask his Dad if they could discuss the use of the family car.
His father took him into the study and said, "I'll make a deal with you...You bring your grades up, study the Bible daily, Get a haircut and we will talk about it."
After about a month the teen asked his Dad if the could talk about the use of the car.
Again his father took him into the study where his father said, "Son, I've been very proud of you, your grades are up, I see you reading the Bible every day, but you haven't gotten a hair cut."
The teen replied, "you know Dad, I've been thinking about my hair. Samson had long hair also Moses, Noah and Jesus is pictured with long hair."
"Yes," said his father, "and everywhere they went, THEY WALKED."
