Shoyoroku - Case 21: Ungan Sweeps the Ground

When Ungan was sweeping the ground, Dogo said,
  "You are having a hard time!"
Ungan said,
  "You should know there is one who doesn't have a hard time."
Dogo said,
  "If that's true, you mean there is a second moon?"
Ungan held up his broom and said,
  "What number of moon is this?"
Dogo was silent.
Gensha said,
  "That is precisely the second moon."
Unmon said,
  "The servant greets the maid politely."
