Heppoko Jikken Animation Excel Saga

Excel Saga is a one-of-a kind work of art that can only be described as the ultimate parody of anime. From the opening credits - a rather odd spoof of Japanese pop videos - to the ending song featuring Menchi the dog singing/barking a plaintive ballad while a human interpreter translates for viewers, nothing is sacred in the world of Excel Saga.
