I think he said he was so awesome, but he preceded it by cracking a joke about his humility so I disregarded it as a joke. It was like he was poking fun at his own ego. Besides somebody else wrote his jokes. He was just reading them.
That's the point, people who hypnotize say something on the surface but the message is subliminal. The real message is in their body language, their cadence etc., it co insides with what they are saying on the surface. It is "embedded". It has to with learning, understanding and then exploiting the way the brain is hardwired to except and process information. It is a science.
As for saying he was just reading what his handlers had written for him, his handlers would have to be involved. He obviously has been handled since who knows when, possibly since he was a child.
