EW is reporting that not only will the chesty chanteuse guest in a Christmas-themed episode, she'll actually be appearing a live-action segment with the Springfieldians present in puppet form. Plus, she'll be Moe's girlfriend! Which is funny! Because Moe is ugly and Katy Perry has large breasts which she often displays prominently!
Why puppets? Why Katy Perry? Why, sweet merciful God, why? I grimly await the episode where Marge becomes a robot.
