Anders briefly quotes Gene Ray, saying "no man on Earth has no belly button", implying that sexual activity took place in the conception of everyone in the world. This implication is subtle, however.

Anders makes violent and threatening references at times.

The word "snot-brain" is used on one occasion.

Many trippy images appear, especially toward the beginning, but nothing explicitly referencing drugs or alcohol.
