'The Bubble Boy'
Aired: Oct. 7 1992
Jerry attempts to visit Donald Sanger, a young fan with an illness that forces him to live in a plastic bubble. George and Susan arrive at the house first, only to discover that the so-called "bubble boy" is a grown man with an attitude problem, living in his parents' house behind "a thin layer of plastic separating the room." George provokes a fight with Donald during a game of Trivial Pursuit ("Moops!") and Susan accidentally pops the "bubble" trying to intervene. Kramer's discarded Cuban cigar burns down Susan's father's cabin. It is later discovered that the only thing that survived the fire was a box of love letters to Mr. Ross from the author John Cheever.
