Check out this video from Japan of a monkey using a vending machine. Not only does he use the machine but he uses it just like a human would! Watch as he smashes the crap out of buttons, almost like he's trying to say "GIMME MY DAMN FOOD!!!". He must have learned from someone who's totally into junk food, even though the monkey is buying grape juice. Glad to see the monkey picked up at least one good habit from learning to use these machines.
