The preacher took the mower and began to crank it. He pulled on the rope a few times with no response from the mower.
The preacher called the little boy over and said, 'I can't get this mower to start.'
The little boy said, 'That's because you have to cuss at it to get it started.'
The preacher said, 'I can't cuss. It's been so long since I became a Christian that I don't even remember how to cuss.'
The little boy looked at him happily and said, 'You just keep pulling on that rope. It'll come back to ya.'
