Shopping for School Supplies the Bart Simpson Way!/References

Trivia

 * Among the things that Bart hides in his binder are a brass knuckle, a can of spray paint, a rubber spider, various straws (for spitballs no doubt), a slingshot, a "kick me" sign, and three comic books.
 * Bart makes a "nerd-chucker" out of two and, ironically, hits Cosine with it. Cosine then says that he "thought angles were [his] friend".

Continuity

 * One of the comics in Bart's binder appears to be Zebra Girl, which first appeared in the Season 9 episode "The Canine Mutiny".
