I'm sure most have read this but I think it's funny. Lifted from cracked.com, think I edited out the swearing.
"As anyone who's been bored enough to watch Animal Planet late at night will tell you, the octopus is a creature of very high intelligence (and occasionally, precognitive powers). But what would happen if they directed all that impressive brain power specifically toward causing trouble? World chaos, probably, because it took one octopus doing that to turn an entire aquarium upside down in Coburg, Germany.
Bored with the unbearable dullness of life in an enclosed tank (and possibly suffering from a little ADD), Otto the octopus is constantly looking for ways to keep himself entertained. And since he lives in an aquarium, he needs to go to great lengths to achieve that, mostly in ways that involve being a jerk to his neighbors. Like when he starts juggling the hermit crabs, or rearranging everything inside the water tank to cause stress to its other inhabitants.
And if that isn't enough, he starts throwing rocks and cracking the glass.
But that's not what made Otto famous -- that would be the time he endangered the entire aquarium. In a fit of boredom, Otto decided he'd had enough of the light shining down on his tank and realized he had the intelligence and the means to do something about it. Swinging himself onto the edge of his tank, he took aim at the light and squirted a jet of water toward it, killing that light ... plus every other light in the building.
Otto's squirt short-circuited the electrical supply to the entire aquarium, which could have had fatal implications for the animals residing in it when the electrical pumps in the tanks stopped working. The aquarium workers fixed the problem as soon as they noticed it ... and then Otto did it again. And again, and again, until the staff held a three night vigil, sleeping on the floor of the aquarium, and finally realized how he was doing it."
