A priest and a nun are on their way back home from a trip when their car breaks down. They are unable to get it fixed, so they decide to spend the night in a hotel. The only hotel in the town has only one room available.
Priest: "Sister, I don't think the Lord would have a problem, under the circumstances, if we spent the night together in this one room. I'll sleep on the lounge and you have the bed."
Nun: "I think that would be okay."
They prepare for bed and each one takes their agreed place in the room. Ten minutes later...
Nun: "Father, I'm terribly cold."
Priest: "Okay, I'll get you a blanket." (He does)
Ten minutes later...
Nun: "Father, I'm still terribly cold."
Priest: "Okay Sister, I'll get you another blanket." (He does)
Ten minutes later...
Nun: "Father, I'm still terribly cold. I don't think the Lord would mind if we acted as man and wife just for this one night."
Priest: "You're probably right...get up and get your own blanket."
