I quote from Dirty.ru:
Traveling through the mountains of Rwanda, a British photographer-animal painter Andy Rose unexpectedly came across a gorilla, methodically kicking alcoholic bamboo juice. After spending a couple of hours in her warm company, Rose learned that the leader of this group silverback gorilla, his name was Kvitondo and that Rwanda remains of these 380 species, but only in the wild a little more than 700. And Kvitondo sitting here in the Virunga Mountains and lamenting his endangered species, drunk three sheets. In the evening, when Kvitondo was already quite wood, Rose went home and returned the next morning, he found a gorilla in a strong hangover. Wisely decided not particularly straining his presence leader, Rose took a few pictures and went on his way.
