They test things out. They toss it against the "wall" and see what sticks. They see what works and what doesn't. They develop a script which they memorize and just stick to it. NO DEVIATION. Whom they are underneath the facade we can never know. We only see what they show and what they show is shaped to please. So clap for them and cheer for them and support them. They are only there to pleasure you and if they do they own you. SIGH.
