Frank Lorenzo cooks dinner for the Bunkers and brings it over, but the table is set for four (Archie, Edith, Frank Lorenzo and Irene Lorenzo) and not six. Mike and Gloria are upstairs, having gone up there after Archie yelled at Gloria for wearing a skimpy outfit, and it was never said they wouldn't be having dinner with the family as always. (Note: Four plates were set due to there being four people in attendance. Presumably, two more plates would've been put out if the Stivics had decided to come down to join them).
