Breeding Bulls
My wife and I went to the County Agricultural Show and one of the first exhibits we stopped at was the breeding bulls. We went up to the first pen and there was a sign attached that said:
THIS BULL MATED 50 TIMES LAST YEAR
My wife playfully nudged me in the ribs ..... Smiled and said, "He mated 50 times last year, that's almost once a week".
We walked to the second pen which had a sign attached that said:
THIS BULL MATED 150 TIMES LAST YEAR
My wife gave me a healthy jab and said, "WOW~~That's more than twice a week! .......... You could learn a lot from him".
We walked to the third pen and it had a sign attached that said:
THIS BULL MATED 365 TIMES LAST YEAR
My wife was so excited that her elbow nearly broke my ribs, and said, "That's once a day .. You could REALLY learn something from this one".
I looked at her and said, "Go over and ask him if it was with the same cow".
My condition has been upgraded from critical to stable and the doctors say I should eventually make a full recovery.

Martin Aircraft Company in 1912 as a manufacturer, and remained for forty years the senior aircraft manufacturer in the U.S. The vast majority of the more than 11,000 planes built by the company before it ceased producing aircraft in 1960, Martin Bombers pioneered the doctrine of airpower in the 1920's to 1930's and served in all theaters in World War II. |
