A preacher was making his rounds to his parishioners on a bicycle when he came upon little Johnny trying to sell a lawn mower.
“How much do you want for the mower?” asked the preacher.
“I just want enough money to go out and buy me a bicycle,” said little Johnny.
After a moment of consideration, the preacher asked, “Will you take my bike in trade for it?”
Little Johnny said, “Mister, you’ve got yourself a deal.”
The preacher took the mower and tried to start it. He pulled and pulled on the rope until he was dripping with sweat but the mower refuses to start.
The preacher called little Johnny over and said, “I can’t get this mower to start.”
Little Johnny said, “That’s because you have to cuss at it to get it started.”
The preacher said, “I’m a man of the church and I can’t cuss. It’s been so long since I’ve been saved that I don’t even remember how to cuss.”
Little Johnny looked at him happily and said, “Just keep pulling on that rope. It’ll come back to ya.”
