I may be watching a little too much of the TV show "Lie to Me", but his body language in that video when he realized what happened, does not say "mild amusement" to me as he tries to indicate with his little joke. His body language to me, seems to say "anger". I just don't think there is any genuine humor or good nature in that man. Maybe I'm just overwhelming biased.
I really like that show!!
Yeah...I thought the body language was "anger" too.
Bet O'Reilly's body language segment on Monday will discuss it....
