Reverend Smith visits Mrs. Jenkins, one of the elder parishioners in his church. Reverend Smith notices that on top of Mrs. Jenkins' organ sits a bowl which contains a condom floating in water.
Befuddled, Reverend Smith asks her to explain this.
"Oh, Reverend Smith," she replies, "I found that lying on the street corner, and the package said that if you put it on your organ and keep it wet that it will prevent disease. Frankly, I haven't been sick all year."
