Secret of Happy married Life

A couple was celebrating their golden wedding anniversary. Their domestic tranquility had long been the talk of the town-"What a peaceful & loving couple".A local newspaper reporter was inquiring as to the secret of their long and happy marriage. "Well, it dates back to our honeymoon," explained the man."We visited the Grand Canyon and took a trip down to the bottom on the canyon by horse. We hadn't gone too far when my wife's horse stumbled. My wife said, "That's once"."We proceeded a little further and the horse stumbled again. Once more my wife said, 'That's twice.' "We hadn't gone a half-mile when the horse stumbled the third time. My wife quietly removed a revolver from her purse and shot the horse dead."I started an angry protest over her treatment of the horse; while I was shouting, she looked at me, and said, "That's once"." And we lived happily ever after"
