So I take the family down to Disney a few weeks back, and I noticed this. In the pre-show for the Aerosmith roller coaster, Steven Tyler shades his eyes with his hand when he first looks at all the people who have happened upon their "studio session", and says "How do, people?" When he puts his hand up to his forehead though, his thumb is tucked and his fingers are extended, except for a curled ring finger. The hidden "shocker" at Disney, replayed over a hundred times a day!
