Hekiganroku - Case 93: Taiko Dances

A monk asked Taiko,
  "Chokei said, 'That is exactly like thanksgiving at lunch.' [1]
   What did he mean?"
Taiko danced. The monk made a deep bow.  Taiko said,
  "What have you seen that makes you bow like that?"
The monk danced. Taiko said,
  "You stupid fox! [2]"

[2]: Cf. the term "fox Zen", which means mere imitation (cf. Case 2 in the
     Mumonkan)
