The Chimney Sweeper Lobby
After the assassination of Tsar Alexander II of Russia, a government official in Ukraine menacingly addressed the local rabbi. "I suppose you know in full detail who was behind it."
"Ach," the rabbi replied, "I have no idea, but the government's conclusion will be the same as always: they will blame the Jews and the chimneysweeps."
"Why the chimneysweeps?" asked the befuddled official.
"Why the Jews?" responded the rabbi.
