An elderly couple, a middle-aged couple and two young newlyweds wanted to join a Baptist church. The pastor told them that new parishioners had to abstain from sex for four weeks. Everyone agreed.
Four weeks later the couples returned. The pastor first asked the seniors if they’d been successful. “No problem at all,” the husband replied, and the pastor exclaimed, “Congratulations! Welcome to the church!”
The pastor then asked the middle-aged couple how they’d fared. “The first two weeks were easy,” the husband told him, “but the third and fourth were pretty difficult. Yet we managed to abstain.”
