Of course, this is typical Arnold.
He had various Nazi marching songs that he used to play to torture Weider with, along with the salutes he would administer on Joe.
Then there was the reverential tones about Hitler in Pumping Iron outtakes, which prompted his purchase of Pumping Iron at a price higher than justified, all in order to ensure that nothing of it ever came out. Then he turned around and recouped some of that price with the 25th anniversary DVD.
Arnold, truly an ahole as well as charismatic and compelling.
