Monkeys are clever - that we know.

So someone gave this monkey some money and asked him to buy something from the vending machine. And this happens:

The monkey puts in the money pretty smoothly - he seems to be pretty smug about it too.

It's time to push the button... And whoa, is he getting a little frustrated!? Yes - you might want to drink right away, but at least look and aim your hands at the buttons!

His desperate action is so hilarious... But he make sure he picks up the change.
