I feel the same way Platapus. Your explanation makes sense.
Those people in the video could well have been just scratching their ear. That's why I thought it far fetched and more likely the product of photo shopping.
Quote from Platapus : Different people will "see" different things depending on their experiences.
A friend , who had gone through Law School had a professor who conducted an experiment. The class all witnessed a " crime " . They were then all told to write down what they saw including a description of the " actor and crime ".
He was amazed at how widely the account of the entire class varied . This experiment was to demonstrate that people see what they want to see, perhaps based on bias. Others had described the event exactly .
