I remember watching a TV show (probably when animals attack) where this guy has a trained bear for many years,he used to hit and prod the bear with a stick to make him obey him,the bear never did anything about until one day the guy hit him and he just freaked and fucked the dude up.
Then there was the idiot who put deer urine on his body to see if he could attract a buck......well he did and that buck didn`t give a fuck.........hooved (is hooved a word....it is now ) his ass to the max all while this idiots wife was filming it.

One more I recall was an elephant trainer,same scenario as the bear...the elephant finally got pissed,threw the guy around like a rag doll stomped him a bit,then broke down a fence and ran amok in the streets.
Some people just tempt fate when it comes to being ballsy with unpredictable animals.
