The Junior Campers is a Scouting-style organization in Springfield. Its aims include teaching Springfield's children outdoor survival skills and encouraging them to be involved in community service. Its headquarters is a single room in an unknown building — possibly Springfield Elementary School, but not verified to be so.
The early history of the Junior Campers is unknown; the organization was not seen or mentioned before Bart Simpson became a member.
Bart's involvement with the Junior Campers began when he and Milhouse Van Houten found a $20 bill on the ground. The two of them then went on a spending spree, among other things purchasing an all-syrup Squishee from the Kwik-E-Mart. After consuming the Squishee, they went hyper from all of the sugar in it. When Bart woke up the next morning in his bedroom, suffering from a sugar hangover, he discovered to his mortification that he was wearing a Junior Camper uniform. Apparently, he had joined the organization while in the throes of his Squishee-fueled binge.
Bart took his uniform to school, intending to turn it to the Junior Campers and back out of joining, explaining that it had been a mistake. However, Mrs. Krabappel announced a surprise quiz, prompting Warren to ask to be excused as he had to attend a Junior Campers patrol meeting. Mrs. Krabappel consented, and Bart, seeing the opportunity to get out of the quiz, hastily donned his uniform and told her that he also needed to attend the meeting, as "this uniform carries certain responsibilities"...
