Three couples, one old, one middle aged and one newlywed, went to the Catholic Church and wanted to become members. The priest told them that this required them to live in chastity for two weeks. The couples agreed, and returned after two weeks. The priest says to the old couple, "Did you manage to live without sex for two weeks"? The old man replied immediately, "No problem, Father". "Welcome to the Catholic Church". Then he turned to the middle aged couple and said: "Did you manage to live without sex for two weeks"? The man replied: "The first week was fine, but the second week I had to sleep on the couch for a couple of nights, but we managed it anyway". "Welcome to the congregation", the priest said. Finally, he said to the newlywed couple, "Well, did you manage to live without sex for two weeks"? "No, unfortunately", said the young man. "We couldn't live without sex for two weeks". "What happened"?, the priest asked. "My wife lost a milk carton on the floor. When she bent down to pick it up, I couldn't resist, and took her from behind". "You know what that means", the priest said, "you're not welcome in the church". "We understand," said the young man. "We are not welcome in Lidl either".
