Here's a similar joke:

A young preacher moves to a new town and decides to look around. So he hops on his bicycle. While riding he comes across a young boy who is selling his lawn mower. The preachers stops to talk to him and says "Hi, I'm the new preacher in town and I sure could use a lawn mower but, I don't have any money right now. If you would like, I could trade you this bicycle for it." The boy brightens and says "I was selling this lawnmower so I could buy a bike! Sure!!"

A little later in the day, the preacher has the lawn mower out and tries to start it. He pulls and pulls and pulls on the cord, but nothing happens. Just then, the boy rides by on his bicycle. "I'm having an awful time starting this thing, how do you start it?" he yells after the boy. The boy stops and says "Well, sir, you've got to give it a good cussing before it will start." The Preacher responds "Son, I'm a man of God, I don't curse. In fact, its been so long I don't think I can even remember how to." The boy replies "You keep pulling on that cord and you will, soon enough."

A young preacher is about to give his first sermon and is quite nervous about it so he goes to the senior preacher to ask his advice.

"You have to have a good opener to grab their attention," the senior preacher says. "one of my favorites is to proclaim that some of the best years of my life were spent in the arms of a woman that was not my wife -- she was my mother. and then I go on to give my Mother's Day sermon."

The young preacher thought that was a great idea and when the big day came the church was packed. He got up into the pulpit and loudly proclaimed "Some Of The BEST Years Of My Life were spent in the arms of a woman that was not my wife!"

But then he got nervous again and his train of thought suffered a derailment. He said the only thing he could think of.

"But I can't for the life of me remember who she was."
