When Rutherford B. Hayes was a student at college it was his custom to take a walk before breakfast.
One morning two of his student friends went with him. After walking a short distance they met an old man with a long white beard. Thinking that they would have a little fun at the old man's expense, the first one bowed to him very gracefully and said: "Good morning, Father Abraham."
The next one made a low bow and said: "Good morning, Father Isaac."
Young Hayes then made his bow and said: "Good morning Father Jacob."
The old man looked at them a moment and then said: "Young men, I am neither Abraham, Isaac nor Jacob. I am Saul, the son of Kish, and I am out looking for my father's asses, and lo, I have found them."
