... high up a mountain. Halfway to their destination, a snowstorm slowly started. They discovered an old wooden cabin and decided to take shelter.
Inside there was only one bunk, but also a sleeping bag. So, as a man, the priest decided to let the nun have the bunk while sleeping in the sleeping bag himself.
After some time in bed, he heard the nun say: "Father, I am soooo cold...". So he got up, found a blanket and gave it to her, then went back to sleep.
Again, after some time he woke again to: "Father, I am still soooo cold...". So, once again, he got up, found another blanket and gave it to her.
Not one hour later, the nun was awake again, complaining about the cold. So he said: "Listen sister, we are in this lonesome cabin, not a single soul within miles. Nobody would ever know what we do here. So, just this once, would you like to spend the night like husband and wife?"
"Yes", she said. "I would like that very much!"
"Well then, ... GET THAT FU#*ING BLANKET YOURSELF!!"
