Jerry's new girlfriend is a Romanian gymnast who won an Olympic silver medal but his expectations about their night together leave him disappointed.

Jerry dates Katya (Elina Löwensohn), a Romanian former gymnast whom Jerry says won a silver medal at the 1984 Olympics, (although if this were confirmed, she would also have won a gold medal as Romanian women took the team title in Los Angeles). Kramer encourages him to have sex with her, since she is probably very "flexible." Jerry can only think of a conversation involving deposed dictator Nicolae Ceausescu.

George is given another shot with Lindsay (Jessica Hecht), whom he met while trying to join a book club to read Breakfast at Tiffany's ("The Couch"); according to George, she finds his stupidity "charming."

Jerry and Kramer find out about one of George's odd bathroom habits: whenever he goes into the "office" he takes off his shirt so as to feel "no encumbrances." Jerry talks about how George is better with the mothers of his girlfriends than with the girlfriends themselves.

Kramer goes to Mr. Pitt's (Ian Abercrombie) office to retrieve a 3-D auto-stereo-gram painting that Elaine took to frame. Kramer leaves early as he feels intense pain which turns out to be a kidney stone. Mr. Pitt becomes obsessed with finding the "spaceship" image in the 3-D painting. In place of Mr. Pitt, Elaine goes to a merger meeting between Morgan Springs and Poland Creek but starts a dispute because of the suggested name "Moland" Springs. Before all this, Mr Pitt had barred Elaine from using fountain pens in the office, as they leave a smear. Mr Pitt was the one who had suggested the name Moland Springs, but when Elaine laughed at it, the respective owners have second thoughts about it.

At Lindsay's mother's house, George impresses Mrs. Enright (Lois Nettleton) with his gentlemanly demeanor, until he is caught by her eating a partially eaten chocolate Eclair out of the trash can. George assures Jerry that the pastry was clean and "on top", but Jerry says George has crossed the border between man and bum by eating trash. George explains his point of view in a phone call and gets another chance with Lindsay.

Kramer brings Jerry a videotape of the 1984 Olympics and Jerry decides to go for it with Katya. Later, Jerry tells Elaine of his disappointment with the sexual tryst (there was nothing gymnastic about it), and she tells him he is now committed to dating Katya for at least three more weeks.

At the street, George buys a cup of coffee, but he does not like it and throws it away, accidentally splashing a nearby automobile. The driver gets upset and demands George to clean the windshield; he is then spotted cleaning the windshield by Lindsay's mother, who is now convinced that he is a bum. George has to apologize once more and gets another opportunity with Lindsay.

Since it was Kramer's idea, Jerry wants Kramer to come along to the circus with Katya and him to watch the performance of Katya's friend Misha (Maurice Godin). However, Kramer is afraid of clowns (see "The Opera"). At the circus's restroom, Kramer finally passes the kidney stone, but he screams so loudly that he makes Misha, the tightrope walker, fall from the high wire.

Katya tells Jerry about a Romanian legend of "the comedian" - a man with great libido - and breaks up with him because he was not the otherworldly "sensual experience" she expected. In Romania the social trend is that you can break up after 3 days of having sex, while in the US Jerry felt obligated to go out with Katya for 3 weeks!!

At Lindsay's mother's place there is a small party, and in the bathroom, they have placed a 3-D painting which is "mesmerizing." George goes into the bathroom, but then forgets to put his shirt back on and walks out of the bathroom topless, which shocks all the other party guests and pretty much ends his relationship with Lindsay.

Mr. Pitt has lost three days trying to see the image in the 3-D painting. He now sees it right before going to an important meeting discussing the merger. Elaine, who has her hands covered in ink from a broken fountain pen, breaks the picture and snaps her boss from the trance. However, she spills ink on him, and he goes to the meeting with a painted mustache, making him look like Adolf Hitler. Aside from the visual humor, the scene alludes to Hitler's invasion of Poland in 1939 through the juxtaposition of the imagery and the bottled water brand name.
