(Strip Number 5015, Original Publication Date, 6 September 1988)
Panel 1: Since he's contractually obligated to ask stupid questions he's gotta know the answers to, John asks Elly what she's doing with the wallpaper and measuring tape she's holding. She gets all closed-eyed and pious and talks about how she's tired of how long the kitchen project has taken and proposes to do the wallpaper herself.
Panel 2: When he points out that it's eight in the evening and that'll mean that she'll be up past midnight, Elly tells him that she's in the mood.
Panel 3: When he asks if she minds his going to bed anyway, she says to go ahead because, as she said, she's in the mood.
Panel 4: Since John is an evil, conflict-causing MAN who wants awful sex, he thought-bubbles that he remembers a time when that conversation would have had an entirely different meaning.
Summary: A thought occurs. Maybe most of why Elly isn't into sex is that after all the build-up about how great it was supposed to be, she wound up singing a torch song afterwards after her first time. The song in question: "Is That All There Is?" by Miss Peggy Lee.
