It is a defense mechanism. There was a study done showing that throwing feces is a sign of higher brain function. In that study they found that the apes (chimps in this study), that threw poop were also the better communicators in the group. It's hypothesized that our ancestors probably threw poop and led to our ability to speak.
They will if they get angry!
really far they can throw as far 200 metres
Only in a zoo where the audience likes to see it happen
It can throw poo at you and jump about angrily.
Yes. Apes actually do throw their own poop.
no it is not true.
Yes, monkeys are like every other animal, and they do excrete.

Yes, at least as much as any other primate. Since their minds are not as developed as ours, it seems that they could be on the maturity level of a toddler. There are toddlers who like playing with their excrement or would do so if given an opportunity. Then they grow out of it. There are also dogs that like rolling around in dog waste. So given the behavior of other mammals, including primates, it is reasonable to believe that there are monkeys that enjoy this as well.
Of course it all makes sense
Yes, monkeys do crap. well what do they throw at people then at the zoo :)
It looks like a nightmare just like you
