    9. ELVIS THE CROC

    Elvis the crocodile does not believe in warnings. When a noisy lawnmower in Elvis's exhibit started bothering the croc, he responded by stealing the machinery and drowning it in his pool. Zookeepers had to wait more than an hour before Elvis abandoned the lawnmower so they could fetch the mangled equipment. (Newser)
