The King Cobra is a pretty bad ass snake, so avoid at all costs.

Wow, that is possibly the worst way in the world to approach a snake. Yelling at the top of your lungs "SNAKE SNAKE SNAKE" and running towards it is only going to frighten it and make it aggresive. Fortunately these "nature" shows normally just plant these animals without their venom, pretending that they found them.
But hey, I live in Australia where I have found in my bedroom plenty of redback spiders (which are among the most deadly in the world), I also currently live right across the road from a conservation park that houses some of the deadliest snakes in the world (my cats have brought into out back yard a total of 4 King Brown Snakes in the last 3 years) and a short walk from the beach which has previously had reports of Great White sightings (and I've found more than a few Blue Ring Octopi in the rock pools).
Pretty much everything is dangerous here.
