Elaine is weary of her co-workers' numerous celebrations with cake, so she calls in sick. Elaine's co-workers surprise her the next day with a cake to celebrate her return to work, but she rejects it and refuses to take part in any future celebrations. Missing the daily sugar-rush, Elaine raids her boss Peterman's mini-refrigerator. She finds a slice of cake and has a bite. Peterman reveals it is from King Edward VIII's wedding to Wallis Simpson, and he bought it for $29,000. Elaine returns to even out the cake, but is swept up by the decadence of eating cake from a royal wedding and ends up finishing it off. Elaine looks for a replacement, and Kramer points out that it resembles an Entenmann's cake. Peterman is bewildered when he has his slice of cake appraised at only $2.19. He reviews his office surveillance videotape and sees Elaine eating and dancing with the slice of cake. However, he decides the effect of such a stale cake on her digestive system is all the punishment she needs. Kramer visits the police station, where he obtains some caution tape and hears about a serial killer who is cutting off people's heads in Riverside Park, nicknamed "The Lopper". Jerry and George visit their nostalgic hangout since high school called Mario's Pizza Parlor, as it is closing from bankruptcy, they both order two last slices of pizzas and two last liters of grape sodas before it closes down. George then spots an old Sega/Gremlin version of the Frogger arcade cabinet that he got a record-breaking high score of over 860,000 points under the initials "GLC". George plans to buy the machine to preserve his fame, but Jerry points out that he must keep it powered up while he moves it, or it will lose its memory, erasing all high scores. George meets with Kramer, expert electrician "Slippery Pete", and truck driver Shlomo to coordinate the movement of the Frogger machine. However, Slippery Pete carelessly plays Frogger on battery power until only three minutes of power remain. The only available power source is across a busy street, and Kramer has run out of caution tape. He looks at his situation, and attempts to roll the machine on wheels across the street while trying to avoid cars, like a game of Frogger. George reaches the opposite sidewalk, but is unable to lift the 382 pound machine onto the curb. A big hauling Freightliner comes and shatters the entire arcade cabinet. Jerry dates Elaine's friend Lisi, who finishes his sentences, but incorrectly. While he walks her home after a bad date, she tells him she lives in the Riverside Park area. To avoid the Lopper, he instead takes her back to his place, where they end up having sex. Lisi plans a weekend trip for them to Pennsylvania Dutch country, a signal that the relationship is getting serious. It is too late for a phone breakup, so Jerry goes to Lisi's apartment and breaks up with her. However, the breakup takes ten hours, so Jerry makes up with her rather than risk going out at night and running into the Lopper. The next morning, they head off on the trip to Pennsylvania Dutch country.
