A priest and a nun are caught in a blizzard.
They find a deserted cabin and take shelter.
They find a sleeping bag, a bed, and a pile of blankets.
The priest, being a gentleman, offers the nun the bed and takes the sleeping bag for himself.
As they get tucked in for the night the nun calls out, “Father, Father I’m cold!”
So the priest gets up and puts another blanket on the nun. “Is that better Sister?” he asks.
“Yes Father, much better,” she replies.
So he gets back in his sleeping bag and starts to nod off when she again calls out with, “Father I’m still cold!”
