Why do they call Yogi Berra Yogi?

He picked up his famous nickname from a friend, Bobby Hofman, who said he resembled a Hindu holy man (yogi) they had seen in a movie, whenever Berra sat around with arms and legs crossed waiting to bat, or while looking sad after a losing game. Years later, the Hanna-Barbera cartoon character Yogi Bear was presumably named after Berra (the cartoon's creators denied it), something Berra did not appreciate after he started being periodically addressed as "Yogi Bear."(Wikipedia) For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated at the bottom of this answer box.
