Have you ever been to the Louisville Zoo? There are several great monkey exhibits. The monkeys play around the exhibit swinging from ropes. So a few things I should tell you before you view this:
1) This was not staged - the boys concocted this on their own.
2) I know this is a choking hazard and should only be done with supervision.
3) I don't believe in evolution, but sometimes I think my kids just might be a little closer to monkeys than humans...
The bananas at the end were just an added bonus that they threw in.
