In "The Sandman Sleeps," when Eustace takes a bite of the egg, he spits it out, but it in the next scene, his egg is magically on his plate!
Muriel: I'm sorry, Eustace. I haven't been myself lately.
Eustace: Well, whoever you are, just get me my toast.
Eustace: Huuuungry! (spaghetti hits him in face)
Voice: Once you lick the God Bone, you cannot stop. It's just that good!
Eustace: (Courage tries to get Muriel to sleep by playing lullabies on a xylophone) Turn off that darn rock-n-roll!
In "Stormy Weather," when Courage was trying to find Dunken, he goes to "Burgers Really Cheap," the restaurant seen in "Heads of Beef."
