Go Fish

And, he's not one out of water, but in the goal:

Comet the goldfish may be the world's most intelligent fish after its owner, Dean Pomerleau, trained it to perform a range of aquatic activities.

Comet can play football, basketball and even limbo dance under a bar.

The genius of the water world can also play fetch with a hoop, slalom around a series of poles and push a rugby ball over a set of posts.

....Dr Pomerleau insisted there was nothing fishy about his claim, saying anyone can teach their pet to perform similar tricks.

"There is mounting evidence that fish are more intelligent than people give them credit for," the fish training expert said.

"With the correct tools and the basic promise of a food reward, fish can very quickly learn complex tricks - like the limbo, slalom or playing fetch.

"Now people in the market for a dog might want to consider a fish instead."
