A man takes his wife to the State Fair and one of the exhibits is that of breeding bulls. They come up to the first pen and there is a sign that says "This Bull mated 50 times last year." The wife pokes her husband in the ribs and says, "He mated 50 times last year."
They walked a little further and see another pen with a sign that says, "This Bull mated 120 times last year." The wife hits her husband and says "That's more than twice a week! You could learn a lot from him."
They walk further and a third pen has a Bull with a sign saying "This Bull mated 365 times last year."
The wife gets really excited and says "That's once a day. You could REALLY learn something from this one."
The husband looks at her and says ....
"Go up and ask him if it was with the same cow."
