The article neglects to mention if they're Maoists, but it's highly likely they are; the photograph of Bruno testifies to the chimp's striking resemblance to the late Chinese leader, and the personal hygiene and patterns of grooming are identical. Well... almost identical; Bruno clearly takes greater pains to cultivate a civilized appearance than did Mao, and perhaps this is the reason the chimp is somewhat more handsome.
The whole hygiene thing--I was thinking they must be French.
