Video: Monkey on Elephanta Island w/ stolen water

We ran into this guy early into our trip up Elephanta Island. The monkey in the video stole another tourist's water then immediately ran behind a tree, unscrewed the lid and began to drink it. These monkeys were very smart.

The incident reminded me a lot of this story about a chimpanzee in south africa who picked up a cigarrette habit after watching zoo-goers who would throw him the occasional half-pack.
