Parasites Lost Deleted Scene
You noticed that Hermes is shown scooping some of Amy's popcorn with a Jai-alai (a scoop-like device used in the sport of Jai-alai) during Fry's colonoscopy, right? This is because it was referencing a deleted scene where he announces that the crew will be using alternative utensils due to the kitchen's plates going missing. Removing that particular scene in the final product makes it an insignificant plot hole.
