A nun was taking the bus. After a while, a hippie came on and sat down next to the nun. Suddenly, the hippie asked the nun if they maybe could have some sex. Naturally, the nun refused and went off the bus on the next stop. Then the bus driver, who obviously had heard the whole conversation, turned around and told the hippie that he knew that the nun went to the chapel every morning at 8 to pray. He suggested that the hippie tried to meet her there. The hippie said thanks to the driver, and decided to give it a try.
Next morning at 8, the hippie went to the chapel, dressed like God. And, as the driver had said, the nun showed up. God (i.e., the hippie) suggested sex, and the nun didn't want to say no to God, so she accepted. But on one condition: as she wanted to keep her virginity, she said that it had to be anal.
After having sex for a while, the hippie took his mask off and laughed: "I'm not God! I'm the hippie from the bus!" Suddenly, the nun took off the mask and answered: "Well, I'm the bus driver!"...
