She tossed one to a medium sized monk; before he could eat it a much larger male was on him and not only stole his peanut but gave him a beating, then left.  The little fellow made no attempt to pursue his tormentor; be squatted at the scene of the crime, pounded his knucks against the concrete floor, and chattered his helpless rage.  Mike watched it solemnly.  Suddenly the mistreated monkey rushed to the side of the cage, picked a monkey still smaller, bowled it over and gave it a drubbing worse than the one he had suffered - after which he seemed quite relaxed.  The third monk crawled away, still whimpering, and found shelter in the arm of a female who had a still smaller one, a baby, on her back.  The other monkeys paid no attention to any of it.
