Lisa's initial tutoring efforts are unsuccessful and so she decides to take the children to downtown Springfield to introduce them to culture in the outside world. However, Lisa's plans are diverted when Krusty spots the kids singing, decides to use them as a musical act for his show, and offers them a contract, which Cletus signs with an "X" (in sharp contrast to his elegant signature in the episode "Sweets and Sour Marge"). Lisa is worried about the way that Krusty and Cletus are exploiting the children with their plans for a national bus "No-Collar Comedy Tour", so she sends an e-mail to Brandine, who is currently a soldier in Iraq. She arrives by helicopter to tell Krusty that the contract Cletus signed is null and void, as he is the father of only two of the seven children — the one who cannot sing and the one who cannot ad-lib. Cletus then tells Brandine that they owe Krusty $12,000, but she assures him that they can live on that, and Cletus is happy to have things back to normal.
