I was watching the hyena march during the "Be Prepared" and I couldn't help but notice that the hyena's marching style of marching is similar towards the Nazi's pose. In the marching scene one of the front paws would be in the air in the way the Nazi's would pick up their legs high during their marching. And it seems to me that when their paws would be in the air t seems that they're saying "Hail Scar" that same way the Nazi's would say "Hail Hitler".
