We moved props from one of the three rings to the next, helped in any way we could, and generally got dusty, dirty, hungry, and tired. During one of the breaks, I started chatting with a man who trains animals for Hollywood movies. When they are babies, we stake them down. They try to tug away from the stake maybe ten thousand times before they realize that they can't possibly get away. At that point, their 'elephant memory' takes over and they remember for the rest of their lives that they can't get away from the stake.
Humans are sometimes like elephants.
