I really had not considered this being a Polish proverb, just something they said and passed on from father to son. Polish for circus is "cyrk" or "sorkus" and often refers to a mess or a strange situation, something chaotic. In Poland monkeys, "malpy" are associated with chaos, trouble, and down right nuisance. So if the monkeys are running around loose or escaping from the circus, well you get the picture. Monkeys are "problems" in Poland, and circuses are where "problems" come from. If it's not your monkey, and it's not even from your circus, then it's not your problem. It is a basically simple philosophy and stops some people from spreading further gossip as well, no one will listen and there they stay with mouth agape.
