(Strip Number 4133, Original Publication Date, 25 February 1982)
Panel 1: We find ourselves watching Elly sit on the arm of John's chair as he reads the paper; as he looks at the sports section, she asks him why he eats twice as much as she does but doesn't gain an ounce.
Panel 2: He ascribes it to his having a less efficient gut.
Panel 3: His telling her that she, on the other hand, absorbs more of what's consumed and that the excess becomes fat does not please her.
Panel 4: We next see the aftermath of his getting smacked over the head with a couch cushion; as he sits there looking as if his head has been replaced by a pillow, he thought-bubbles "Lesson Number 768: Never answer a loaded question."
Summary: Lesson Number 769 is, of course, don't try to side-step said question: Elly's need to complain about how awful her life is cannot be denied; if he'd tried to soften the blow by telling her that he likes his women to look like women and not stick figures, he's a pig. If he tries to plead the fifth, he's a liar and a shnook. Either way, he's going to be eating down.
