Trivia: When Homer starts tripping on the chili pepper, he sees a distorted vision of Ms. Crabapple and she makes "wah-wah-wah" noises when she talks. These are the same noises teachers are always making in Charlie Brown cartoons.
Continuity mistake: This is a mistake for the introduction from seasons 2-20 (1991-2009). When Homer screams, he turns round. You see this in a wide shot. There are no boxes to the right of the door in the garage. However, two just appear out of thin air when he runs through the garage. (00:01:50)
