This YouTube clip shows a highly intelligent Monkey living in isolation within the confines of a Jail like enclosure at the Nakhon Ratchasima Zoo in Nakhon Ratchasima, Thailand. His release into the wild would allow him to live a life of happiness & freedom instead of suffering a lifetime of mental torture & deprivation. This sweet little soul fashioned himself a Hammock from a towel that was used for bedding in his cell & strung it between the bars above the cage flooring.   https://www.youtube.com/watch?v=rlM5cokIm00
