Shoyoroku - Case 56: Misshi and the White Rabbit

When Uncle Misshi [1] and Tozan were walking together, they saw a white rabbit
run by in front of them. Misshi said,
  "How swift!"
Tozan said,
  "In what way?"
Misshi said,
  "It is just like a person in white clothes [2] being venerated as a prime
   minister."
Tozan said,
  "You are such an elderly and respectable man, and still you say something
   like that?"
Misshi said,
  "Then how about you?"
Tozan said,
  "A noble of an ancient house is temporarily fallen into poverty."

[1]: Somitsu Zenji, uncle to Tozan Zenji. "Misshi" literally means "Master
     Mitsu."
[2]: I.e., a commoner, or a person without any social status.
