A princess and her entourage are playing a truth-telling game.
She asks a knight if he has fathered any children. He looks down and says, “Alas, my Lady, I have not.”
The princess nods. “I believe it. You do not have the look of a man who could please his mistress. Your beard is a mere fuzz, and it is easy to tell from the state of the hay whether the pitchfork is any good.”
On his turn, the knight asks, “Lady, answer me without deceit. Is there hair between your legs?”
She playfully replies, “None at all.”
“Indeed I do believe you,” the knight smiles, “For grass does not grow on a well-beaten path.”
