Notes:

• The pregnancy of Richie and Lori Beth's second child is unresolved.
• 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 7 and 11, 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 the newlyweds, 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 to them "Thank you all 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.
