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. Even though I don't have any scales I do have balances, and for a weight I use a one-pound loaf of bread that I buy from this baker."
