First appearance of Comic Book Guy, Mrs. Glick, Radioactive Man, Fallout Boy, and Bartman.
When Martin makes a squealing noise while falling in the treehouse, Bart calls him "Piggy" and threatens to stuff an apple into his mouth, resembling a similar quote from "The Lord of the Flies".
The warning from the convention MC not to ask questions about the death of Radioactive Man's actor Dirk Richter is a reference to the mysterious death of Superman's actor George Reeves, although the addition of bordello could also be a reference to the unsolved 1978 murder of Bob Crane.
Mrs. Glick was based on an old lady Jeff Martin and his brother used to do chores for when they were kids. Martin said they got to "pull weeds until [their] hands would bleed", and yet they were only paid two quarters for several hours of work.
