read a few of Arnold's books..and one of the things that stood out
was just how competitive a guy he is/was.

At some stage, when all the bodybuilders are on stage together...it becomes a
really competitive sport....guys bumping each other out of the way..strategically standing and posing
next to certain others to highlight their shortcomings.

Arnold was even known(and he shows photos) to tell other guys jokes to blow their concentration.

He would outpose guys, who were bigger or more symmetrical than he was.
