Housemaster is the crudely-drawn, bread-headed protagonist of the "Arfenhouse" series of computer games and Flash movies. He lives in the crudely-drawn Arfenhouse with his crudely-drawn lover Good Kitty (formerly Evil Kitty), and his crudely-drawn friends Piakchu (sic), Woogy, and Dog. There's also Joe, Housemaster's long-suffering and better-drawn neighbor from another, better game that got scrapped. Joe is also the only one who seems at least halfway sane.
Housemaster's adventures are pure nonsense, not helped by the fact that he and his friends (except Joe) communicate mainly in garbled "noob-speak", an obscure dialect of leetspeak with much worse spelling.
