So there was this country preacher, visiting a parisheners farm, who happened to catch young Johnny behind the barn, "doing his own thing".
"Young man", he said, "don't you think you should save that for when you get married?"
A few years go by, and the same pastor marries Johnny and his bride. After the wedding, he gets Johnny aside and asks, "did you follow the advice I gave you?"
"Yes, I did"
"Now, aren't you glad?"
"To tell the truth, not really; I've got two cream cans of the stuff, and I got no idea what to do with it..."
