Complete story — includes the ending

Pete flirts with a high school student in his driver's education class, but she calls him old and rejects him. Pete and Trudy host a dinner party for the Cosgroves and the Drapers; Pete feels jealous of Ken's writing success, as well as Don's handyman skills at fixing their leaky faucet. After watching England win the 1966 FIFA World Cup Final, Lane attempts to land an account with Jaguar Cars. Edwin, the Jaguar representative, persuades Don, Roger, and Pete to visit a local brothel, during which Edwin, Roger, and Pete cheat on their wives. The next day, Edwin withdraws from SCDP after his wife finds out about his infidelity, causing Lane to blame Pete's methods for losing the account. In response, Pete questions Lane's role at the firm, leading to a fist fight between the two men; Lane wins, leaving a bloodied and humiliated Pete on the office floor. Joan comforts Lane, who misinterprets her affection and kisses her. Roger bluntly tells Ken to stop writing, as he should not be diverting any attention from his job. Ken suspects Pete informed Roger and continues to write under a new pen name. In the elevator, Pete talks about his despair at the day's events to Don. Close to tears, he confesses that he has nothing, while Don remains silent.
