It seems like everyone's done a "Saw" parody by now. There should be a trope for that. I liked the animation. I really had no idea what would happen next. Yep, even the very end. I knew the tape would tell him to shut up, so I guess it wasn't prerecorded after all.
Or maybe it was. Dang, was there a lot of housework to do. Well, it's like that of course. I don't recognize the other characters. I haven't seen too many of these cartoons.
