Episode #150 - The Bunker's unexpected return from a weekend trip puts Edith in a precarious situation when she discovers that Teresa has her boyfriend in her bedroom. Edith and the embarrassed Teresa agree that the only course of action is to try to sneak out the visitor before Archie finds out.
Archie is shocked when his coworker Stretch has died after cavorting with a young woman. Asked to give the eulogy, he enlists Mike's help, requesting Bible references. But the biggest shock comes at the funeral.
Mike and Gloria have an argument after a Scrabble game about Mike always being right and that she never did get to go to college as Mike had promised. Mike also ends up with Archie as a roommate for one night.
Archie, Mike and Gloria plan a surprise party for Edith to celebrate her 50th birthday. But an unwelcome visitor to the Bunker's home - while Edith is home alone - has a much different surprise in mind for the Bunker matriarch.
A power outage and reports of looting in the city prompt Mike to write a letter to the editor about how greedy governments do the same in the name of free enterprise. At the bar, Archie vents his frustrations about how Mike always argues his point and doesn't see things his way. Two men - who have been listening in - approach Archie and suggest that he come to a meeting of the Kweens Kouncil of Krusaders (a chapter of the Klu Klux Klan), where they will come up with a more severe way of "teaching" Mike a lesson.
Archie learns that Gordie and Mitch - the two men he met earlier at his bar - plan to burn a cross on the Stivic's lawn and must come up with a way to stop them. When Archie tries to persuade Mike to write a new letter to the editor (recanting his previous stance on free enterprise), he lets slip that he had spoken with known Klu Klux Klan members. Mike is outraged and tells Archie to go away, but Archie is still determined to stop the cross burning - even if it means he will be the KKK's next target.
A flashback episode of when Mike and Gloria first came together by mutual friends at the Bunker home while Archie and Edith are out. Initially their differences lead to much tension until they discover a shared love for old style dancing.
