(Strip Number 387, Original Publication Date, 14 April 1983)
Panel 1: We start things off with Mike reminding John that they've gone to nine houses and only sold three chocolate bars.
Panel 2: They then run into that common-place of suburbia called "the dog tied up in the front yard to scare off night-time intruders and annoy the holy living shit out of letter carriers and milkmen."
Panel 3: We next watch Mike ask an irritated John if he's stepped in something; this is because Mike is better able to keep himself from stepping in the dog crap that dumbasses like the Pattersons don't scoop.
Panel 4: John then mournfully thought-bubbles that his one bad night helping his son go door-to-door gives him (temporary) respect for postmen.
Summary: Watch Lynn totally not get that we say 'letter carrier' now; watch Lynn also say something totally unrelated to anything that isn't whining about being inconvenienced by the little strangers who want to be the boss of her.
