Reverend Billy Graham don't even know the way to the post office. Category : Pastor and Priest Jokes The Reverend Billy Graham tells of a time early in his ministry when he arrived in a small town to preach a sermon. Wanting to mail a letter, he asked a young boy where the post office was. When the boy had told him, Dr. Graham thanked him and said, "If you'll come to the Church this evening, you can hear me telling everyone how to get to Heaven." "I don't think I'll be there," the boy said. "You don't even know your way to the post office."
