3 couples want to convert to Christianity and join a church. The minister has them go to services, meet the congregation, go to socials, etc. After a few months, he tells them "The last part of this process, to really test your commitment to god and to our church, is for you to not have any sex for the next two weeks, then come back to my office and we'll talk about it and see how you fared. After two weeks, they return to the minister's office. He asks them how it went. The first couple, in their 70's, tell him it was not much of a problem, and the minister welcomes them. The second couple, in their 40's, tell him that it was difficult, and by the fourth day they had to sleep in separate rooms, but somehow managed to get through without having sex. The minister congratulates them and welcomes them into the church. The third couple, 20-something newlyweds, complain to the minister, and the husband says: "On the third day, my wife was reaching up to the top shelf for some lightbulbs and dropped them. When she bent over to pick them up I couldn't take it anymore and we made love on the floor right then and there!" The minister, quite shocked, says: "You know this means you're not welcome in this church." The wife say's: "Yeah, that's too bad, but you know what's worse? we're not welcome back in Safeway either!"
