A nun is walking down a dark street one evening when all of a sudden a mugger grabs her and drags her into the bushes.

He has his way with her, then says, “Now what are you going to tell your Mother Superior?”

The nun said, “I will tell her that I was walking down the street and you dragged me into the bushes and raped me twice.”

The mugger said, “But I only raped you once.”

The nun said, “What?, you’re already tired?”
