Angry Lion

I've worked in a zoo (with primates, if you were curious). Most of the animals are very well socialized towards people and are fairly tame. They see keepers and zoo-goers all day long so they grow very accustomed to humans.

I have NEVER seen an animal, predator or not, react this way towards one person for no apparent reason. That guy should be very glad he's behind strong glass. YIKES!
