There is also similar story about Komodo Dragon. Guy buys a big lizard, tries to communicate with it, teach tricks, all to no avail. Then one day the lizard bites him out of the blue. Guy is angry at the lizard, swears to give it back to the shop the next day. Then he notices the lizard is following him with it's head down. Guy warms up to the lizard "Finally you show remorse! Understood that biting me was a bad idea, huh?" After several days of that following he decides to call the vet about it. And the vet explains to him that the lizard is simply waiting for him to die from the bite.
