And where do I wind up? In a dungeon!

From A Treasury of Jewish Folklore by Nathan Ausubel.

An Unpredictable Life

One day, centuries ago, as a rabbi was on his way to the House of Study he suddenly met the duke of the province followed by his retinue.

“Where are you going this bright morning, Rabbi?” the duke asked him sarcastically.

“I’m sure I don’t know, Your Grace,” replied the rabbi with a doubtful air.

“You don’t know where you’re going? How dare you speak so impudently to me, Jew? I’ll teach you to have proper respect for a Christian prince!” cried the duke, and he ordered the rabbi thrown into a dungeon.

“What did I tell you, Your Grace?” called out the rabbi. “Now you see for yourself that I was right when I said I did not know where I was going.”

“How so?” asked the duke curiously.

“You see, Your Grace, I left my home this morning in order to go to the House of Study — and where do I wind up? In a dungeon!”
