This episode shows that the zap platform have designated spots for each role, and users will take on different roles if they zap into a dimension on a spot that's designated for someone else's role.
Though not the first time for switched roles of the main cast (the villains do this in "Hail Larry"), this is the first episode where the part-time heroes switch roles, Boone becoming the hero and Penn becoming the wise man.
The specs are shown to have the ability of recording everything that the user sees, like Sashi's time at school.
Sashi is revealed to have a crush on a student named Teddy.
The Body World is a reference to the 1966 film Fantastic Voyage.
The episode is similar to SpongeBob SquarePants episode "Squidtastic Voyage" Where SpongeBob and Patrick travel inside of Squidward's body by accident.
Both episodes, Boone, SpongeBob and Patrick are ends up in Penn and Squidward's bodies.
Boone, SpongeBob and Patrick's mission, Cure the sick patient is Penn and retrieve Squidward's clarinet reed.
Penn almost dies in this episode, triggering his newfound fear of death.
