Jerry goes to pick up Elaine who is “house-sitting” Mr. Pitt’s apartment. On his way in Jerry has an awkward conversation with the doorman, played by real-life friend Larry Miller. Walking down the street, Kramer, with the thought that it would entertain German tourists on a tour bus, simulates robbing George, but ends up invoking fear in them instead. After George’s parents’ separation (“The Chinese Woman”), Frank Costanza is living with George. Jerry doesn’t want to face the doorman again; he wants to wait until the doorman leaves so he and Elaine can go to the movies. However, Mr. Pitt calls from Scotland and Elaine must stay to check the mail. Walking down the street Jerry finds the doorman, who incidentally is standing outside his own apartment building.
Later at Monk’s Cafe Kramer mentions how George’s father has man breasts (“real hooters”), and that he may use some undergarment for support. George freaks out at the idea that it may be hereditary. Kramer leaves to further work on his idea. Elaine tells Jerry that the doorman accused him on harassing him up to his building. Jerry says the doorman is playing mind games with him.
Again at Mr. Pitt’s building Jerry encounters the doorman also in the night shift. Jerry apologizes, saying he is not used to doormen, and just wants to be friends with him. The doorman leaves Jerry in charge while he goes out quickly to buy a beer. Jerry feels the pressure of being a doorman, even signs a package, but as the doorman is taking too long Jerry leaves his post and heads to Mr. Pitt’s apartment. At George’s Kramer presents Frank a prototype for the man breasts’ supporter. On their way to his apartment George talks with his mother to convince her to take back Frank. He also questions her about his grandma’s bosom size. When Jerry and Elaine step out the elevator the police are there because a couch was stolen from the lobby. When George and his mother arrive at his apartment they catch Frank trying on the undergarment.
Jerry thinks the doorman set him up; Jerry and Elaine try to think of an alibi. At George’s, Kramer and Frank think on going into the bra business with Sid Farkus (“The Sniffing Accountant”); Kramer likes to call his invention “the Bro”, although Frank prefers “the Manssiere”. At Mr. Pitt’s building lobby Elaine says nobody will believe a doorman’s word, but he has the package with Jerry’s signature as evidence. Later at Monk’s, Elaine says they must replace the stolen couch, and George suggests they should take his, because then his father won’t have a place to sleep on and he will have to move back with his mother. Jerry recalls that was the couch Poppie peed on (“The Couch”), and George took while just turning the cushions. Kramer and Frank make a deal with Sid Farkus, a bra salesman, until Farkus implies he would like to invite Frank’s estranged wife to dinner.
Without the couch Frank doesn’t know where he is going to sleep, but at the same time he realizes George had him sleep on urine. As George’s mother arrives she starts fighting again with Frank because she is going to dinner with Sid Farkus.
Later, as Kramer walks the street carrying a stereo, the same German tourists who he had tried to “entertain” earlier see him and try to stop him in a scene alluding to Marathon Man. Kramer manages to stave off the anger in the crowd by introducing “the Bro” to them. At Mr. Pitt’s building Jerry and Elaine have delivered the couch. Poppie happens to be in the building visiting a friend. Poppie recalls how the last time he had his problems was because of Elaine’s stand on abortion (“The Couch”). Thus, when he sees Elaine he cannot control himself and “sits” again on the couch.
In the last scene George is sharing the bed with his father, who offers to share a bowl of Kasha. George turns the offer down and goes to bed, but Frank turns on his lamp, preventing George from sleeping.
