Millard Fillmore became president when Zachary Taylor died after either getting poisoned or after eating too many cherries. Nobody really knows. They exhumed Taylor's body in 1991 but the lab results were inconclusive. When Fillmore died in 1874, his last words were reportedly, “The nourishment is palatable.”
