(Strip Number 1629, Original Publication Date, 16 August 1989)
Panel 1: A while later, we see Mike come in and tell Elly that the heat is driving him crazy.
Panel 2: As he grabs a soda out of the fridge, he tells her that the mower is hard to push and that he needs something to drink.
Panel 3: She looks out the window as he says that a person can get overheated mowing lawns on a day like those so he should stay inside for a while.
Panel 4: She replies by telling him that maybe he should mow one of the lawns first.
Summary: The problem with Elly's logic is that she's in her nice, air-conditioned little nook not aware of things like 'heat warnings.' Most of the country has been under one for a month or so so we're dealing with a buttload of bad timing.
