Ever hear the one about the couple who had been married for 60 years? Someone asked the husband what the secret to longevity in marriage was. He said his wife was a woman of no nonsense from Texas. He said he learned very early on what the secret was on their honeymoon. He said for our honeymoon we went to the Grand Canyon and like all tourists we took the mule ride to the bottom with my wife leading the way. At one point the mule stumbled and my wife almost fell off. She told the mule, "That's once!" A little further on, the mule stumbled again and my wife said, "That's twice!". A little further on the mule stumbled again. Without saying a word, my wife pulled out a .357 magnum and shot the mule in the head killing it instantly. I protested greatly and asked why she would intentionally kill an innocent animal! My wife said - "That's once!"
