In the Exeter Book there are some riddles or enigmata. They use double-entendre, whereby one answer is suggested but another is meant.
A curiosity hangs by the thigh of a man, under its master's cloak.
It is pierced through in the front; it is stiff and hard and it has a good standing-place.
When the man pulls up his own robe above the knee, he means to poke the head of his hanging thing that familiar hole of matching length which he has often filled before.
