(Strip Number 490, Original Publication Date, 1 November 1983)
Panel 1: We start things off with John and Lizzie at some other person's house. Since Lynn is sort of a jerk, she has John say "Trick OR treat" and Lizzie "Tricker treat" to highlight her belief that children speak sloppily and need to be constantly lectured as to the problem.
Panel 2: The lady of the house tells John that he looks to be a little old for this.
Panel 3: John says "Huh?" because he doesn't know where Lizzie is.
Panel 4: As he slumps off in defeat, he growls "Next time, you ring the doorbell and I hide in the bushes" at Lizzie.
Summary: For God's sake, man, use your bloody head. You know that Lizzie is terrified of strang....oh, wait. He doesn't know crap-all about his children because he doesn't want to. He doesn't see a little child who freaked out at a strange face, he saw a brat who tricked him into making himself look foolish.
