So these two nuns are walking through the forest, Sister Precise and Sister Logical. It begins to get dark, and they're still a long way from the convent. They realize they are being followed:
Sister P: Sister, do you realize there's a man behind us? He's very large and scary looking, and at this rate he's going to catch up with us in less than four minutes! What do you suppose he wants?
Sister L: Well, it's only logical: he wants to rape us and kill us. Walk faster!
Sister P: Sister, he's walking faster than I can walk! He'll catch us in less than a minute!
Sister L: Then we must do the logical thing. Start running!
Sister P: I can't run as fast as he can! He's going to catch us!
Sister L: We've got to be logical - let's split up! He can't chase us both!
Sister P goes one way and Sister L goes the other. The rapist chases Sister Logical. Sister Precise reaches the convent out of breath, frantically worried about Sister Logical. Finally Sister L arrives, and Sister P lets her in.
Sister P: What happened? I was so worried when he chased you!
Sister L: Well, it's only logical - he caught me.
Sister P: Oh, my Lord! What happened then?
Sister L: I did the only logical thing: I lifted up my skirts.
Sister P: Oh, no! And what did he do?
Sister L: The logical thing, of course. He took down his pants.
Sister P: Oh, my stars! And then what?
Sister L: Don't be silly. A woman with her skirts up can run twice as fast as a man with his pants down. It's only logical.
And for those of you who thought this was going to be dirty: Say two Hail Marys.
8-D
Bingo! We have another winner!
In love and laughter,
