Watch World's Weirdest Season 4 Episode 5 Online

Nat Geo WILD explores nature as it gets rolling drunk and spaces out, and delves into the importance, or lack thereof, of intoxication in the animal kingdom. Meet monkeys that binge drink and throw frat parties, elephants that go on drunken rampages through villages and lemurs that get high off millipedes. And when a jaguar's hunting skills may have been enhanced by chewing on psychedelics, scientists question whether or not there are evolutionary benefits to psychoactive compounds.
