A British Jew is to be knighted by the King.

He is to kneel in front of him and recite a sentence in Latin when he taps him on the shoulders with his sword. However, when his turn comes, he panics in the excitement of the moment and forgets the Latin. Then, thinking fast, he recites the only other sentence he knows in a foreign language, which he remembers from the Passover seder: "Ma nishtanah halailah hazeh mikol haleilot." Puzzled, His Majesty turns to his advisor and whispers, "Why is this knight different from all other knights?"
