Humorous jokes, ask the countryside?

It is said that once upon a time, a man traveled to the countryside and asked an old man what time it was. The old man looked at the cow's breasts and said it was two o'clock. The man was surprised and asked him how he knew the time through his breasts. The old man told him to squat down and said, "Move this cow's breasts a little, and you can see the clock opposite."
