Revealing mistake: At the circus as the clowns appear you can see a composition error on Homer's body. Homer's body is indexed to be as a background scene for several seconds where you can see the man's head fully who is sitting in front of Homer but you can just see that the man's head is in front of Marge's body. You will also see the clown's shoes walk over Homer's body before they update Homer's body correctly. (00:05:19)
