Rob and Jerry, and by association Laura and Millie, aren't speaking to each other over an argument concerning Jerry and Millie's vigilante mentality of wanting to spray weed killer on a neighbor's crabgrass-infested lawn without his consent, of which Rob and Laura want no part. In their argument, Jerry rips Rob's jacket; two weeks later, they're still not speaking. Rob thinks he's extended an olive branch by sending a written invitation to the Helpers to attend a dinner party at their house. In not hearing back from Jerry and Millie, Rob thinks he and Laura have been snubbed; however, the invitation failed to get mailed, which Mel finds almost a week after the scheduled dinner party and posts it for Rob. When the invitation arrives at the Helper's on a Saturday, with the invitation stating that the dinner party is being held this Saturday (but was actually the week prior), Jerry fumes thinking Rob purposefully sent the invitation to arrive the day of the dinner in order for them not to show. After Millie convinces Jerry to go to the dinner party (which is non-existent since the actual dinner party already occurred), the feud may escalate over the misunderstanding; however, the misunderstanding itself may actually solve their problem.
