Many thats funny... Aggressive. Cheeky Monkee... Bet it hurts when they bite..
Damn straight. Big, sharp teeth. I do work in SE Asia and it never fails to amaze me that in tourist areas (Bali's Monkey Forest Road in Ubud, e.g.) parents will give their kids peanuts to give to the monkeys and let them crawl all over their kids. As soon as the food is gone, they turn aggressive, and I've seen little kids get bitten pretty bad, as well as monkeys steal keys, glasses, etc.
