Panel 1: It appears that back in 1992, someone had supplied Lynn with the car ads; this is because Mike is walking down Main Street checking out cars and pointing out a weakness in Lynn's attempt to modernize things. While we're supposed to looking at late model cars, I'm not sure they make some of the models he's admiring.
Panel 2: This continues on for a while.
Panel 3: He then boasts that if he sees a car, he can guess the make and model. As he puffs himself up, Martha greets him.
Panel 4: Since he has car on the brain, he angers her because he has to forcefully reminded of her first name. He'll never see the break-up coming. He's an ass. He deserves this.
Summary: Leopards can't change their spots. Mike will never be anything other than an ass-scratching twerp who blames everyone but himself for his suffering because his takeaway is that expecting him to be blamed for anything 'means' that Martha is playing games with him.
Also, howtheduck will be taking over until the strip for 3 June 2021, disjointed continuity and all. Enjoy his take on Mike's overreach and default belief that relationships are about who deserves to inflict pain and cruelty.
