At the US Open, George gets a hot fudge sundae. He is oblivious to his messy eating getting broadcast on TV, with the commentators making jokes at his expense.
At Pendant Publishing, Elaine must use the company's car service to cross town. Weary of overly talkative drivers, Elaine gets just such a driver, and resorts to faking deafness to shut him up. Reacting to the driver getting dispatched to pick up Tom Hanks, Elaine blows her cover and gets chastised for her deception.
Jerry is transfixed by a beautiful lineswoman, and resolves to "become one of those guys" who can chat up women from a cold introduction. Not realizing that she is deaf, he rants at her for ignoring him, but realizes his mistake in time.
Elaine, wanting to prove that she is "not a terrible person", gets the driver concert tickets through Kramer's connection to make amends. Since Jerry is now dating Laura, the lineswoman, Kramer asks to try out to be a ball boy for the tournament finals. He is mocked for being the only adult contender, but puts the competition to shame as he tirelessly bounds after balls for hours.
George's girlfriend Gwen breaks up with him; he sees through her excuse of "it's not you, it's me", which he considers his own signature, but fails to get the truth from her. Finally learning about his ignominious, widely-watched TV appearance, he assumes this was Gwen's real reason, because he would have done the same himself. Everyone argues whether George or Gwen must now back out of a party they were all going to.
Having nothing else to do, George goes to dinner with Jerry and Laura, where she shows off her lip reading skills. George proposes to Jerry that Laura help him decipher Gwen's true thoughts at the party. They hide their lips from Laura by pantomiming eating, drinking, and fidgeting, but Laura follows along easily and agrees before they can ask her. Jerry shoots down Newman and Elaine also asking to enlist Laura's help. Laura misunderstands Jerry saying "six" for "sex", throwing her lip reading into question.
Elaine lets everyone use the car service for the party; the talky driver, temporarily deafened from Elaine sending him to a Metallica concert, assumes she pranked him and throws them all out.
At the party, Kramer deploys his rusty sign language skills to relay Laura's signed lip reading. As the host invites Gwen to help him sweep together after the party, Kramer reports that they are going to "sleep together", and George hastily confronts them. After the confusion is cleared up, Kramer and Laura blame each other in a signing frenzy that pokes George in the eye.
At the finals, Kramer, pursuing a ball, leaps headfirst into Monica Seles, ruining her comeback by injury. Laura is picked up by the talky driver, who is immediately suspicious at another deaf passenger.
