A British Jew is waiting in line to be knighted by the Queen. He is to kneel
in front of her and recite a sentence in Latin when she taps him on the
shoulders with her 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 nishtana
ha layla ha zeh mi kol ha laylot."

Puzzled, Her Majesty turns to her advisor and whispers, "Why is this knight
different from all other knights?"
