(Strip Number 4874, Original Publication Date, 13 October 1987)
Panel 1: Thelma tells Elly Ed's name as a means of properly introducing him.
Panel 2: She then explains that they're of a kind as they have similar likes and dislikes and have much the same background.
Panel 3: She's very happy that she's able to properly introduce him to her.
Panel 4: This occasions Ed stage-whispering the fact that she wants him to meet with Elly's approval.
Summary: Elly, I should think, was thought of as practice for dealing with his children who might have objected to his "cheating" on their mother.
