John took his missus Sheila to the local animal show and one of the first exhibits they stopped at was the breeding bulls. They went up to the first pen and there was a sign attached that said, "This bull mated 50 times last year." Sheila playfully nudged John in the ribs and said, "He mated 50 times last year."
They walked to the second pen which had a sign attached that said, "This bull mated 120 times last year." Sheila gave John a healthy jab and said, "That's more than twice a week! You could learn a lot from him."
They walked to the third pen and it had a sign attached that said, in capital letters, "This bull mated 365 times last year." Sheila, so excited that her elbow nearly broke John's ribs, said, That's once a day.You could REALLY learn something from this one."
John looked at her and said, "Go over and ask him if it was with the same cow."
