"Never poke a mean bear with a short stick." It means DON'T BE STUPID! ----Japanese Admiral Yamamoto poked a mean bear with a short stick when he engineered the attack on Pearl Harbor on December 7, 1941. Soon after the attack, the Japanese were celebrating their great victory having sunk and damaged so many U.S. ships in the early morning raid. To this the Admiral lamented, "I believe that all we have done is to awaken a sleeping giant and fill it with a terrible resolve."
