(The opening of Nostalgia-Ween begins with a stop-motion segment of Jack Skellington dressed as the Nostalgia Critic as he runs through a forest and comes across the holiday trees of Christmas and Halloween. A third door stands between them with the Nostalgia Critic's face on it. Jack looks at the door with intrigue and opens it. Suddenly, someone holds a gun out and shoots him. The shooter reveals himself as Pennywise from It.) Pennywise: Wah-hah! Wah-hah! Wah-hah! Wah-hah! Wah-hah! Wah-hah! (Jack lies dead as the Nostalgia-Ween logo appears.) (We then cut to a box being placed on a counter.)
