A farmer got married and was riding home from church with his new bride in a horse and cart. Part way home the horse stumbled before righting itself and carrying on. "That's once" muttered the farmer quietly, shaking his head. Soon after the same thing happened again. "That's twice" said the farmer quietly, again shaking his head whilst his new wide sat quietly by his side. Before they made it back to the farm the horse stumbled for a third and final time. The farmer pulled up, slowly retrieved a shotgun from underneath his seat and calmly shot the horse dead. Aghast his bride said "well I think that was a little uncalled for, just because the poor thing stumbled a few times." The farmer sighed and muttered "that's once".
