At a movie theater’s restroom, Elaine, realizing she does not have any toilet paper left, asks the woman in the next stall (Jami Gertz) if she has any toilet paper to spare, but the woman refuses, claiming that she “can’t spare a square.” Elaine pleads with the woman, but she leaves, ignoring Elaine. The woman returns to her seat, and is revealed as Jerry’s girlfriend, Jane. Elaine is shown returning to her seat, with her new boyfriend Tony (Dan Cortese). The two women tell their dates about what had just happened.
At Jerry’s apartment, Kramer walks in, asking to use Jerry’s phone. Jerry accuses Kramer of using it to call a telephone sex line. Elaine comes into the apartment, and describes to Jerry the incident that occurred at the movie theatre. Jerry realizes that the woman that Elaine was bickering for toilet paper was Jane. He tries to defend Jane, while not letting Elaine know that it was her. Meanwhile, George becomes enamored of Elaine’s boyfriend, claiming that “He’s such a cool guy”. Jerry suspects that Elaine dates Tony only because he is attractive, and that Tony is a “male bimbo”, or a “mimbo” for short.
At the coffee shop, Tony, and George plan on going rock climbing together, which excites George, but Kramer is invited by Tony when he enters, and George starts fearing that Kramer will become better friends with Tony than him. Jerry and Kramer tease George about this later, claiming that George is in love with Tony, which George quickly denies. Jane calls Jerry’s apartment, and Kramer answers the call without Jerry knowing. He talks to Jane, and after giving the phone to Jerry, he says that her voice sounded “flinty”, and tries to remember where he has heard it before.
Later, Elaine calls Jerry on his buzzer to tell him that she’s coming up, while Jane is still there. Still trying to keep the two from conflicting, Jerry panics to disguise Jane’s voice by saying that it smelled from the lunch they just had, and gave her many pieces of gum, muffling her voice to an unrecognizable level.
On Tony, Kramer and George’s rock climbing trip, Tony gives Kramer a rope to tie a knot to keep him from falling, but Kramer gives the rope to George, and then distracts him by asking him for food. Tony begins to climb again, but does not know that his harness is not tied onto the rock, and he falls down the mountain. A few days later, Kramer and George tell Elaine what had happened. Upon hearing the news, Elaine quickly asks the two if there was any damage to his face, and is told that he hit his face on a large rock. She rushes to Tony’s house, to see that his face is completely bandaged. He tells her that he cannot remember if the doctors said if there was any long-term damage to his face. At that time, George walks in to apologize to Tony about the trip, but Tony says that he does not want to see him anymore.
While Jerry and Jane were at Jerry’s apartment, Kramer walks in and is introduced to Jane for the first time. He starts to act strangely at the sound of her voice, and quickly refuses to split a taxi to go uptown. When she leaves, Kramer claims that her voice closely resembles that of “Erika”, one of the girls on the phone sex line that he has been frequently calling, but Jerry doesn’t believe him. In the beginning of this scene Jane is giving Jerry a massage to which he replies, “Boy, I’ve been waiting for this.” It is a reference to an earlier episode of this season, The Masseuse, where Jerry is dating a masseuse who will not give him a massage.
At the coffee shop, Kramer is sitting at a table by himself, saying to Jerry that he made a date with Erika, to prove that she is in fact Jane. When Jane arrives, Jerry is shocked. She moves to Jerry’s table instead of Kramer’s, but Kramer still persists on calling her “Erika”, as he and Jerry confront her, claiming that she “sells sexual pleasure over the phone”. She dispels the claims by saying that she sells paper goods. Elaine hears Jane’s voice and realizes that she was the woman who refused to give her any spare toilet paper. Jane then says that she needs to use the washroom, and Elaine races her to the door. There is then a camera angle of the washroom stalls very similar to the one used at the beginning of the episode. Jane’s voice is heard asking the woman in the stall next to hers, whom she doesn’t know, if she has any toilet paper, but is revealed to be Elaine, who tells Jane that she “can’t spare a square”. Jane then realizes that this is the same woman from the movie theater, and Elaine runs out of her stall, carrying many rolls of toilet paper. After exiting the restroom, Jane tells Jerry to never call her again, and then she turns to Kramer and says for him not to call her either, in a sultry voice. Jerry and Kramer then look at each other, stunned.
