What Does PC Mean?

One day a young man was out working in a field on the farm where he lived.
He looked up and saw the letters "PC" in the sky. He immediately thought that God was telling him to "Preach Christ," so he went off to Bible School.
After he had been there for a little while, it became obvious that he "didn't have it" so the school president called him in to his office. He asked the young man why he felt that he should be a preacher, so the young man told him the story of seeing the letters "PC" in the sky.
The school president, with great wisdom, told him that maybe the letters "PC" meant "Plant Corn."
That young man went back home to work on the farm and, with the money that he made there, became a great blessing to preachers and missionaries around the world.
