don't make it a bigger deal than it is.
I am not 100% sure if it is an actor or not, but Letterman has met and interviewed many thousands of people, and if it was real...he should be able to sense somebody being seriously uncomfortable and show some class by letting the fellow off. We don't know this ''shy'' person, he may not even be shy or a social phobic. He may actually be mentally slow and got intimidated by Letterman and the audience members laughter. Anyways, lets not add to this persons possible misery....he didnt explode and die on the spot, he went to a show i'm sure he wanted to attend, and life goes on. Those that know him personally should just tell him he looked great on tv and tell him that they wished they had the courage to sit up front and talk to a celebrity on live tv as well as he did. People should stop picking apart this guys ''15 minutes of fame'' and learn a lesson from it: be mature and show compassion and class in a similiar situation.
