It's John, being an unappreciative boor. Gee, what a surprise.[/sarcasm]
Panel 1: We see John working on the sink. As he does so, Elly tells him that Connie says that she believes she and John have a near-perfect relationship.
Panel 2: She goes on to say that of all the couples that Connie knows, the Pattersons are the only example she can think of as being a real working relationship.
Panel 3: As he takes the sink out, he says that he'll buy that.
Panel 4: That's because he never worked so hard in his life.
Summary: This is where the Wheel of Morality would tell us that John is too big a jerk to appreciate the good things in life, good things being defined as "being married to Flapandhonk." This is also the first example of Pattersons being praised to the skies for doing what they're supposed to do.
