Panel 1: Aaaaand just so we know that plumbers and other people who do manual labor are low-class and uneducated, he says "yer" instead of "your" and drops a 'g'. And I wonder if the clog will turn out to be the work of the Patterspawn, or of Melville flushing his cigars. And IRL, people usually get the hell out of the way when a laborer is doing his thing.
Panel 2: Yep, Kelpfroths. And more hick talk.
Panel 3: In five, four, three...
Panel 4: Oh, come on. First of all, no real person would be aggravated by the sound of someone working on the pipes. Second of all, even if they were, they wouldn't wait until the guy had finished up to start BAM BAM BAMing. And third of all, this would not have continued more than a week at most if someone, either one of the Pattersons or Lovey, had said in so many words, "Stop the banging; it's rude." Instead of sneaking around in their garbage to find plaster.
Panel 5: Ha ha. There MUST be a solution to this. If I could just think what it is.
