The change in partners leads the Simpson family to begin arguing and aggressively competing against one another. The tournament takes place, and in the stands are leading tennis professionals Andre Agassi, Pete Sampras, Venus Williams, and Serena Williams. At the tournament, Homer ditches Lisa for Venus. In response, Marge replaces Bart with Serena as her partner. Ultimately, Serena and Venus replace Marge and Homer with Sampras and Agassi, respectively. This forces the family to go back to the bench and resume their normal places in the family. As they enjoy the exhibition of top-class tennis, they agree that it is better to watch things than to do things, and Homer offers to buy the family dinner with money he took from Sampras' wallet.
