(Strip Number 6140, Original Publication Date, 23 September 1984)
Panel 1: We start things off in the washroom watching Mike humming to himself as he puts a small bar of soap into a tray.
Panel 2: He then puts the tray on the vanity.
Panel 3: He then reminds Elly of that little basket of guest soaps in the downstairs washroom.
Panel 4: The reason he asked is that he remembers that she said they were all dusty and she didn't know how to clean them.
Panel 5: He says that he found a way to clean all of them.
Panel 6: She praises him for his being thoughtful and asks what he used to clean them with.
Panel 7: Judging from the fact that a freaked-out John is holding his toothbrush while foaming at the mouth, I think we can guess what he used.
Summary: While she never went out of her way to line her Sunday strips up with the others, coincidences like that can be entertaining, can't they?
