On the first day back to school, Lisa wins a spelling bee and is recruited by a well-known spelling scout, Joe Beadle. Meanwhile, Homer is distraught after Krusty Burger offers a limited-time Krusty rib sandwich, only to promptly remove it from the menu.
Homer temporarily forgets the sandwich by hustling bar patrons around Springfield, challenging them to a spelling duel with Lisa. Once Homer discovers that Krusty's rib sandwich is scheduled to appear in neighboring Shelbyville, he abandons his scam and travels around the country (a la Deadheads in the '70s) following thesandwich from town to town.
Upon arriving at the National Spelling Bee, the Chair of the Bee asks Lisa to take a dive and let the much cuter boy win. The Chair tells her that she can go to college for free if she takes the dive. Lisa is about to give in, but her morals take over, only she loses anyway when she spells a word wrong, losing the Bee and the scholarship opportunity.
When she gets home however, the town of Springfield erects a monument to her for accomplishing more than anyone else has in the history of the town.
