Catch the Thief
Tzu Hu once late at night shouted in the lavatory, "Catch the thief! Catch the thief!"
In the dark he ran into a monk; he grabbed him by the chest and held him, saying, "Caught him! Caught him!"
The monk said, "Master, it's not me."
Hu said, "It is, but you just won't own up to it."
