The Chief

The Chief appeared in a short cut-away clip titled Diet Tips which played in the episode Phil, which he starred in alongside Detective Shoehorn. PSH points out that the clip has "nothing to do with Space Tree and really has no business being here", which is true. In it, The Chief puts Detective Shoehorn on the case of finding his kidnapped wife. The plotline was never continued beyond that, so we'll never find out if his wife was rescued or not, who knows, she probably fucking died.
