<P> American journalists had in the past covered "bubble boys" who lived in quarantine due to an immune deficiency . The coverage often played for sympathy, ignoring anything about the subject other than his medical condition . In contrast, the bubble boy in this episode (voiced by Jon Hayman) is rude, selfish, and impossible to sympathize with . He is never seen fully on - screen, except for a pair of gloves that he uses to reach through the barrier; when he is shown exiting the house on a stretcher, he is partially covered by paramedics . The Bubble Boy also appears in the final episode of the series . He tells the court the story of what happened and George yells "it was Moops!" </P> <P> Jerry, George, Elaine, and George's girlfriend Susan plan to travel upstate to Susan's family's lakeside cabin . In the coffee shop, Elaine and Jerry meet a kindly father (Brian Doyle - Murray) who describes the sad life of his young son Donald who lives in a "plastic bubble" (a plastic divider which creates a germ - free sterile environment). Because Donald is a fan of Jerry's, Jerry is forced by Elaine to visit Donald on the way to the cabin to cheer him up . However, Jerry gets lost and George and Susan arrive before him . While waiting for Jerry to arrive, they play Trivial Pursuit with the "bubble boy ." </P> <P> The Trivial Pursuit game ends prematurely when George disputes the answer to the question: "Who invaded Spain in the 8th century?" Donald answers "the Moors," but--due to a misprint or deliberate copyright trap--the question card says that the answer is "the Moops ." George refuses to give Donald credit, causing Donald to attack him . As Susan tries to defend George, she punctures and depressurizes the bubble, inadvertently causing George to be accused of trying to kill him, since he was the one struggling with Donald . </P> <P> While this is happening, Jerry and Elaine decide to exit the highway and go to a diner . It turns out that a waitress (O - Lan Jones) is a fan of Jerry's as well . She asks for an autographed picture of Jerry, who was mispronounced as "Gary Seinfield ." Jerry does not like what he writes, so he asks for it back . The waitress refuses, and it escalates to the point of the waitress attacking Jerry in the same manner Donald attacked George . However, this is interrupted by a man who announces that Donald was attacked by a "bald man from the city" (George), who claims that Donald tried to kill him, and that his house is right down the street from the cafe . Jerry and Elaine meet up with George and Susan at the house before being chased away by the residents of the town, who targets George for revenge . </P>
