A man takes his wife to the stock show. They start heading down the alley that had the bulls.
They come up to the first bull and his sign stated: "This bull mated 50 times last year." The wife turns to her husband and says, "He mated 50 times in a year, you could learn from him."
They proceed to the next bull and his sign stated: "This bull mated 65 times last year." The wife turns to her husband and says, "This one mated 65 times last year. That is over 5 times a month. You can learn from this one, also."
They proceeded to the last bull and his sign said: "This bull mated 365 times last year." The wife's mouth drops open and says, "WOW! He mated 365 times last year. That is ONCE A DAY!!! You could really learn from this one."
The man turns to his wife and says, "Go up and inquire if it was 365 times with the same cow."
"A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks." --Thomas Jefferson, letter to Peter Carr, 1785
