In Broke Joy's Figurine Joy wanted Earl to buy her a hot tub. If she was on his list for ruining getting a free hot tub he could have bough her one and crossed two list items.
Joy puts pickle slices on her eyes while relaxing in a hot tub however in real life the vinegar in the pickles would have resulted in a burning or singing sensation but Joy is a stereotypical "dumb blonde" character so this sight gag was done for comedic purposes.
