George shows off the new key ring that George Steinbrenner has given everyone in the Yankee organization, celebrating Phil Rizzuto's induction into the Baseball Hall of Fame. However, George loses his new key chain. George theorizes that he may have lost his keys when he did a broad jump over a pothole that has now been paved over. George, unwilling to pay the city maintenance crew, dons construction gear and takes a jackhammer to the pothole in order to reclaim his key chain.
Jerry accidentally knocks his girlfriend Jenna's toothbrush into the toilet, and she uses it before he can tell her. Jerry plans to secretly sterilize his girlfriend's mouth, but despite his attempts, he just can't get past the vision of the toothbrush in the toilet. Jenna finds out about the toothbrush and sticks something of Jerry's in his toilet, refusing to tell him what it is. Jerry throws out nearly everything he owns, suspecting that anything could have gone in the toilet; he finally learns that the mystery item was nothing more than his toilet brush. Digging for his Phil Rizzuto keychain, George accidentally strikes a water main while digging up the road, causing an eruption that sends water bursting out of Jenna's toilet, soaking her.
Kramer complains about the failing highway infrastructure after running over an abandoned sewing machine, so he adopts a one-mile piece of the Arthur Burghardt Expressway through the Adopt a Highway program. Kramer works diligently to keep his part of the road clean, not trusting the work to the city's maintenance crew. Kramer repaints the four-lane highway, intending to make it a more luxurious two-laner, but his efforts only result in mass confusion and congestion on behalf of the drivers. Kramer attempts to return the highway to its original state, but spills paint thinner all over the pavement.
Elaine tries to order a new Chinese dish, Supreme Flounder, but she lives across the street from the boundary of the Chinese restaurant's delivery area. Elaine schemes to get her Chinese food by moving into a janitor's closet, located in the building across the street. The building's superintendent believes her to actually be the janitor and pesters her about the maintenance that needs to be done. Elaine has the gang over for dinner in the janitor closet she's moved into temporarily. Elaine, still acting as the janitor in order to allay any suspicion, brings the building's garbage to the dump in Jerry's car, swerving all over Kramer's luxurious two-lane highway and unknowingly dropping an old Singer sewing machine on the road. Newman drives by in his mail truck, delivering crates of fish. His truck catches Elaine's sewing machine and drags it along the highway, sending up sparks that ignite Kramer's paint thinner and cause his truck to go up in flames.
