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.

Sashi is revealed to have a crush on a student named Teddy.
The Body World is a reference to the 1966 film Fantastic Voyage.
Penn almost dies in this episode, triggering his newfound fear of death.
