Dagwood rehearses telling Blondie that he resigned. Blondie puts an apron on Dagwood and goes to Dithers. Neighbor Marvin Williams (Don Beddoe) asks Dagwood to go fishing.

Neither Blondie nor Dagwood will leave first, and they make up. They go to buy the property but can't. Dithers returns and is glad they couldn't, saying they can go on vacation.
Bumbling Dagwood makes absurd errors in normal suburban
life, and his harmless flirtation triggers explosive jealousy
in Blondie, allowing middle-class audiences to see their daily
activities botched up for laughs. Yet there is a stable security
in their life-style that not even their goof-ups can sabotage,
giving the spectators comfort and amusement too.
