A new priest has just arrived and is interviewing one of the nuns. She tells him they've had a terrible time lately. First, the Germans came thru and raped all the nuns except sister Ann. Then, the Spanish came thru and, again, raped all the nuns except sister Ann. Then, the French. Again, sister Ann was spared. "Tell me" said the priest, "Why is sister Ann immune to the depravities of these barbarians?" "Well", she said, "Sister Ann doesn't go in for that sort of thing!"
