Three couples wanted to join a local church

I thought this, from Mark Elrod's Lame-O Weblog, was cute:

Three couples - one elderly, one middle-aged and one newlywed - wanted to join the local church. The pastor told them that the church had a special requirement for new parishioners. He said that each couple had to abstain from having sex for two weeks as a sign of their commitment to the Lord's work. They all agreed and returned to the pastor's office at the end of two weeks. The pastor went to the elderly couple and asked, "Were you able to abstain from sex for the two weeks?" The old man replied, "No problem at all, Father." "Congratulations! Welcome to the church!" said the pastor. The pastor went to the middle-aged couple and asked, "Well, were you able to abstain from sex for the two weeks?" The middle-aged 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, yep, we made it." "Congratulations! Welcome to the church," said the pastor. The pastor then went to the young couple and asked, "Well, were you able to abstain from sex for two weeks?" "No Pastor, we were not able to go without sex for the two weeks," the young man replied sadly. "What happened?" inquired the pastor. "Well, the other night, my wife was reaching for a can of coffee on the top shelf and dropped it," said the young man. "When she bent over to pick it up, I was overcome with lust and we had sex right there on the floor." "You understand, of course, this means you will not be welcome in our church," stated the pastor. "That's okay," said the young man. "We're not welcome at the Wal-Mart anymore either."
