(Strip Number 4345, Original Publication Date, 15 July 1983)
Panel 1: We start things off with Laura telling Mike and Liz that the mother cat and her kittens are only barn cats that are kept around to kill mice. (This, of course, doesn't stop them from wanting to take a kitty home.)
Panel 2: She then points out the farrowing pens and where the feeder pigs are kept.
Panel 3: She then points out their prize boar. Danny keeps him penned up by himself for reasons that would tend to escape the seven year old mind.
Panel 4: His grim jest about how it's a honeymoon suite also tends to sail over their heads. Oh, sure, they have some idea that he's made a dirty joke but they don't quite get it.
Summary: This, I should think, would be described by some sort of variation of "This is the truth. This occurred as I wrote it." Mind you, it didn't happen to anyone that didn't graduate high school but this probably did happen.
