Drugs can do some crazy things, man.

This guy, who was definitely high on something, decided that he wanted to be Tarzan for the day. So what did he do? He headed over to the Santa Ana Zoo in California, took off his shirt and attempted to climb into the monkey exhibit so he could swing around in the trees with his wild animal brethren. After covering himself in mud, he managed to get into the trees and refused to come down.

Not surprisingly, the zoo did not take kindly to his behavior, called 911, and the man was arrested.
