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 , and trying to ' stop 9/11 ' as said by Cletus . 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 can not sing and the one who can not ad-lib . The story ends with Cletus telling Brandine that they owe Krusty $ 12,000 , but Brandine tells him that they can live on that , and Cletus is happy to have things back to normal
