“Here is one for you to consider,” said Master Lu to Acolyte Wei. “Would it be better to own a stopped clock, or a clock that is one second too slow?”
“I would imagine that the slow clock would be preferable for obvious reasons,” replied the acolyte.
“Ah,” said the master, “but while the slow clock is always wrong, the stopped clock is right twice a day.”
“But the slow clock is slow by such an insignificant amount of time that it is basically as good as an accurate clock,” said Wei. “And anyway, how would you be able to tell when exactly the stopped clock was right?”
Master Lu contemplated this for a moment, and then got up to leave.
“Where are you going?” asked Acolyte Wei.
“I have to go try and get my old clock back,” the master replied.
