Coconutting monkeys mean business

Coconut pickers who are monkeys. This is the tagline. A person in Thailand has 2 monkeys trained to get coconut off trees. They get around 300 coconuts per day per monkey, about 10 times more than what a person could get.
The coconuts that the monkeys collect prove to be so money earning to their owner that they paid off their purchase cost within a month, and have paid for the college expenses of their owner's kids. With such trained helpers, the owner is very careful to keep the monkeys in good humour, not even shouting at them even if they bite him.
