What starts a great opportunity for Jerry soon becomes a nightmare in "The Puffy Shirt".
Jerry, while helping Elaine with a charity event, is at dinner with Kramer and his new girlfriend Leslie, who is a clothing designer. The chatting goes well... except for when Leslie speaks. Because neither Jerry or Elaine can hear what she says (she is dubbed a "low- talker"). When Kramer leaves to use the restroom, Jerry and Elaine are left alone with Leslie, who asks a question. Jerry and Elaine answer in the affirmative.
Meanwhile, at another dinner, George is with his parents on the first night after he is reduced to having moved back home. Needing to get some air, he runs into a woman, who stops him and presents him with an unexpected opportunity.
"The Puffy Shirt" does start out slowly. George is upset at the turn of events in his life at the beginning, but midway he's hook, line, and sinker in his new profession (maintaining the necessary appearance). The significant moment in this episode comes when Kramer brings over the titular item. Which Leslie has created- and expects Jerry to wear it. Because he's helping to promote Elaine's benefit show to help the homeless- live on the Today Show.
The laughter that will come from this keeps building and building, including a sort-of reference to season four's "The Contest", when the story of the person previously in George's position is told. And the end is one of a few episodes where EVERYONE is directly affected by the outcome- in this case of Jerry's mortifying appearance on the Today Show (with then-cohost Bryant Gumbel as himself).
