I lived in Jakarta as a kid but never saw one of these shows in that time. If I did, I'm sure I would've thought it was fun and amazing at the time myself being so young. Not sure what they do to the monkeys exactly though the second clip seemed to be a little more revealing with the chain. There's no telling what they do when people aren't watching. :/

My parents are watching, just this once, pretend you're Tattoo and see the plane...
