It was illogical for Edith being MIA in this story.
Barney says he saw Sammy Davis Jr. kiss Archie on the cheek in the second season All in the Family episode "Sammy's Visit." No he didn't. Archie had already chased him out. It was Munson the cab driver who took the picture of Sammy kissing Archie and witnessed by Edith, Mike, Gloria and Lionel Jefferson. (Note: Barney may have meant that he had seen the picture that Munson had taken).
