Two military policemen were chasing a fleeing draftee from the military base. The draftee ran into the courtyard of a convent. He saw a nun seated on a round bench beneath a tree, quietly reading a book.
He said to her, "Quick sister, please hide me I don't want to be drafted and the M.P.'s are chasing me!"
She lifted up her skirt and said, "Quick hide under here."
The two policemen came by and asked if she had seen anyone. She replied, "No."
After they left she told the young boy to come out and that everything was going to be OK.
He thanked her and said, "You have a nice set of legs for a nun!"
She replied, "If you'd have reached up a little farther you'd have found a nice set of balls too. I'm not going to be drafted either!"
