So a priest and a nun were traveling together. They came to a small town just at nightfall, with only one small hotel, full of cars. The hotel only had one room left, but it had two beds so they took it.
It was a cold winter night, and the heater wasn't quite keeping up. After the light was out, the nun said "Father, I'm cold."
The priest silently got up, got her another blanket, and went back to his bed.
After a little bit the nun said "Father, I'm still cold."
The priest got up and got her a second blanket, again without saying a word, and went back to bed.
There was a short silence, before the nun said "Father, I'm still cold, and the blankets aren't helping. Do you think, just this once, it would be okay if we acted as man and wife?"
There was a long thoughtful pause, and the priest said "well... I suppose if that's what you want.
Get up and get your own damn blanket."
