A man took his wife to the Rodeo and one of the exhibits is that of breeding bulls. They went up to the first pen and there was a sign that said, "This bull mated 50 times last year." The wife poked her husband in the ribs and said, "He mated 50 times last year." They walked a little further and saw another pen with a sign that said, "This bull mated 120 times last year." The wife hit her husband and said, "That's more than twice a week! You could learn a lot from him."
They walked further and a third pen had a bull with a sign saying, "This bull mated 365 times last year." The wife got really excited and said, That's once a day. You could REALLY learn something from this one." The husband looked at her and said, "Go up and ask him if it was with the same cow."
