A preacher was making his rounds to his parishoners on a bicycle, when he came upon a little boy trying to sell a lawn mower.

"How much do you want for the mower?" asked the preacher.

"I'm just trying to make enough money to buy a bicycle," said the little boy.

After a moment of consideration, the preacher asked, "Will you take my bike in trade for it?"

The boy said, "You got a deal."

The preacher took the mower and tried to crank it. He pulled on the string 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 'cause you have to cuss at it to get it started."

The preacher said, "I'm a minister, and I can't cuss. It's been so long since I've been saved that I don't know if I even remember how to cuss."

The little boy looked at him happily and said, "Just keep pulling on that string. It'll come back to ya!"
