Nellie The Sea Otter is Really Good At Stacking Cups

It's amazing what you can teach animals. They act like they aren't as smart as us, but with a little work, they can do what we can.

So much for being top of the food chain. First they teach them to stack cups, next they'll know how to over throw us. Then we'll be serving under our sea otter overlords. Okay, maybe that's a bit irrational, but you never know.

It just proves that if they are given the proper tools, and training, animals can do some pretty impressive stuff.
