The Sheep Farmer
After the first day, they had successfully castrated 14 sheep and his French worker was just about to throw away the 'parts', but the sheep farmer yelled, "No! Don't throw those away! My wife fries them up and we eat them. They're delicious and we call them 'sheep fries'."
Later that day, the French hired hand came in for supper and indeed, the 'sheep fries' were tasty.
The next day, they castrated 16 sheep, and the following evening they all settled down to another supper of 'sheep fries'. The third day, however, when the sheep farmer came home, he asked his wife where the French hired hand was.
She said, "You know, it was the weirdest thing! I told him since there weren't very many 'sheep fries' this evening, we were also going to have French fries. Then he screamed and ran like hell."
