[S3E13] Play It Again, Bonnie
Once again, Jack doesn't want to spend money even when it becomes apparent that he's going to have to. It's a familiar story, heightened by the audacity of Karen calling Jack cheap to his face. What's more interesting is the bigger issue at play: Jack doesn't want to let go of the family car because of all the memories that go with it. We see the Arnolds washing the car as a family, and it is one of the rare times that they're all getting along, making Jack's hesitance to let go more understandable.
