Note: This episode is loosely based on the 1965 Dickey Lee hit "Laurie (Strange Things Happen)," which itself is based on the urban legends known as the vanishing hitchhiker and Resurrection Mary; and because of it, the episode also reflects the teen death song phenomenon from that period.

When it appears the Cunninghams are planning to sell their home (so Howard can accept a job as vice president of a hardware store chain based in New York state), Fonzie may have to leave, too. Fonzie eventually gets his own apartment and adjusts to his new life

Notes:

• The series finale originally aired as a one-hour episode; in syndication, it is aired as a two-part episode. Though this episode is the finale, several earlier unaired episodes were burned off by the network during the coming summer months. The finale was filmed on Stage 19 at Paramount Pictures Studios on November 27 & 28, 1983.
• Potsie and Ralph are the only two characters in the original cast who did not attend Joanie and Chachi's wedding.
• At the beginning of his speech to toast newlyweds Chachi and Joanie Arcola, Howard mentions that "Both of our children are married now," officially writing Chuck (from Seasons 1 and 2) out of existence.
• Howard ends his speech, as well as the episode (and thus the series), by "breaking the fourth wall," looking directly into the camera and thanking viewers "for being part of our family" before raising a toast "to happy days." Afterward, a closing montage of classic clips from past seasons is played over a portion of "Memories" by Elvis Presley, before a final shot of the current cast celebrating Joanie and Chachi's marriage.

Special guest stars: Ron Howard as Richie Cunningham; Al Molinaro as Al Delvecchio; Ellen Travolta as Louisa Delvecchio; Cathy Silvers as Jenny Piccalo; and Lynda Goodfriend as Lori Beth Cunningham.

Absent: Anson Williams as Potsie Weber.

Marion and Joanie spend a weekend with Marion's mother
