A photographer could bear-ly believe his eyes when a bear started waving at him. The friendly animal wandered to the front of his enclosure before sitting back in full view of zoo guests. He then lifts his powerful paw and excitedly waves in an almost human-like way at his new audience. The hilarious encounter was captured by keen photographer Andrey Slepnev, 31, while on a trip to Madrid Zoo, Spain on March 24, 2016. (Photo by Andrey Slepnev/Caters News)

Artist Pyotr Pavlensky sits on the wall enclosing the Serbsky State Scientific Center for Social and Forensic Psychiatry after he cut off a part of his earlobe during his protest action titled “Segregation” in Moscow October 19, 2014. Pavlensky protested against the usage of forensic psychiatry for politically motivated purposes. He cut off his earlobe to demonstrate how authorities could “cut off” an unwanted individual from society by using psychiatric and medical diagnosis to forcefully send a person to a penitentiary hospital, according to Pavlensky.
