(Strip Number 4843, Original Publication Date, 15 August 1987)
Panel 1: As they drive home, Elly tells John that she doesn't mind using Phil's car but does object to the bric-a-brac tied to it because Lynn's first wedding dress got covered in ink because Doug's friends got stupid.
Panel 2: She then sets up the group stupid by pointing out the dumpster he lost his watch in.
Panel 3: John tempts fate by calling himself clever in avoiding an unnecessary trip to the nuisance grounds only to stop short. When he starts to panic, Elly asks what's wrong.
Panel 4: The rest of the family panics when he asks where the car keys vanished to.
Summary: The funny thing about John is that he's in the habit of losing car keys all the time. Just searching for 'keys' shows us that John is always losing the keys someplace.
