The scene in which recruitment officers enter public schools in an attempt to recruit children is based on real life, as the Army has often sent recruiters to high schools for seniors. More recently they have started with the younger grades even though there is a minimum age for enlistment. The show also featured the last (living) appearance of Johnny and Vern, the vaudeville performers; Stewie shoots them because, as MacFarlane comments, "people were getting sick of them", with David Goodman adding that "the show was relying on them too much". The duo return in "Back to the Woods", with Vern as a ghost and Johnny in Hell.
