A baker in a little country town bought the butter he used
from a nearby farmer. One day he suspected that the bricks
of butter were not full pounds, and for several days he
weighed them.
He was right. They were short weight, and he had the farmer
arrested.
At the trial the judge said to the farmer, "I presume
you have scales?"
"No, your honor."
"Then how do you manage to weigh the butter you sell?"
inquired the judge.
The farmer replied, "That's easily explained, your
honor. I have balances and for a weight I use a one-pound
loaf I buy from the baker."
