When Chao-chou was traveling around, he came for an interview with Lin-chi. Lin-chi was just then washing his feet.
Chao-chou asked, "What did the Patriarch have in mind when he came from the west?"
Lin-chi said, "As it happens, I'm just now washing my feet."
Chao-chou came close and made as though listening.
Lin-chi said, "All right then, I'll throw out a second dipperful of dirty water!"
With that, Chao-chou turned and left.
Commentary
The smell alone should have told Chao-chou that trouble was coming. If only he had trusted his nose instead of his ears.
