Dont Argue with your Dad?

A teenage boy had just got his driver's license and inquired of his father
as to when they could discuss his use of the car.

His 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 a little, and get your hair cut.
Then we'll talk about the car.'

The boy thought about that for a moment, decided he'd settle for the
offer, and 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 got 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.'

To this his father replied, 'Did you also notice they all walked
whereever they went?
