Three couples - an elderly couple, a middle-aged couple and a young newlywed couple all had recently moved into a new community and all wanted to join the local church. The three couples met with the pastor of the church and after some pleasant conversation the pastor felt that all three couples were likely candidates for his parish. 

"You all seem like lovely people." said the Pastor. "However, we have one special requirement for new parishioners. You must abstain from having sex for two weeks." 

The couples agreed that this was an acceptable probationary measure and decided to return at the end of two weeks. Two weeks pass and again, the three couples meet with the pastor. The pastor approached the elderly couple and asked, "Were you able to abstain from sex for the two weeks?" The old man replies, "No problem at all, Pastor. Our faith helped us persevere." 

"Congratulations! Welcome to the church." said the pastor. The pastor looked to the middle aged couple and asked, "Well, were you able to abstain from sex for the two weeks?" The man replied, "The first week was not too bad. The second week I had to sleep on the couch for a couple of nights but, yes, we made it." 

"Congratulations! Welcome to the church." said the pastor. Finally, the pastor approached the newlywed couple and asked, "Well, were you able to abstain from sex for two weeks?" 

"Well Pastor, we were not able to go without sex for the two weeks." The young man replied. 

"What happened?" inquired the pastor. "My wife was reaching for the "Weetabix" on the top shelf and dropped it. When she bent over to pick it up, I was overcome with lust and took her right then and there." 

"You understand of course, this means you will not be welcome in our church," stated the pastor.
