While visiting the Memphis Zoo, one family had the treat of the seeing the alpha male monkey in action. When they walked into the cafe which has a glass window to the monkey, the alpha started acting up because he saw the father as a threat.

The monkey ‘ninja-flipped’ off a tree and tried to take him down, but of course there was the thick glass window. Mom laughed at the monkey’s reaction, but the baby didn’t think it was funny at all and cried. The video is going viral, thanks to being posted on 22Words
