What is this anime called?

In this anime that shows on adult swim, there's this middle school boy who lives with his father, grandfather (or some old man) a TV-headed robot, and this flamboyant pink-haired housemaid who was apparently some alien from a distant. This anime has fast-paced plots and even faster dialogue (well, I have a hard time keeping up with it.) So, does anyone know the title of this weird show?
