The video portrayed the typical white liberal and their behavior, but also part of it was just typical [human] reaction to something out of the norm. Yes it was a little exaggerated, but I’ve seen that behavior before. However, it’s not too funny witnessing this, but it is funny watching it on video. Video has that effect, sometimes even without the exaggerated effect added.
When I was in the Navy we produced a video of our deployment. Various shots of everyday life of a ship-at-sea. One shot was of Sailors coming through the chow line the, Sailor didn’t see the camera, but you could see his expression when he looked at the food, he then squinted his eyes and took a closer look and then suddenly jumped back and said: WHAT–IS–THAT!?!
No one on the video laughed and the guy behind the line just stood there and shrugged his shoulders. When that was shown on CCTV everyone just lost it. It was one of the funniest things I’ve seen, but in retrospect I’ve seen that reaction all the time – we all have done it in response to Navy chow. But for whatever reason watching it on video was extremely funny.
