Bart and Milhouse argue about the existence of the Butterfinger food group.
Milhouse asks if he can trade lunches with Bart, but Bart doesn't want to, as he has the four food groups: sandwich group, cow group, jungle group, and the Butterfinger group. Milhouse protests that there isn't a Butterfinger group, but Bart tells him about it. Milhouse is sad because he doesn't have the Butterfinger group.
