Marge: It's almost lunch time. Do you know where your brother is
tutoring?
Lisa: Pfft. Tutoring? The only thing Bart's teaching is guerilla
combat in Shelbyville.
Marge: Well, do you have a number where we can reach him?
Lisa: No, Mom, Bart and some kids ran off to wage war on Shelbyville!
Marge: [gasps] Homer! Come quick! Bart's quit his tutoring job and
joined a violence gang!
