(Strip Number 4437, Original Publication Date, 4 August 1984)
Panel 1: We find ourselves watching Elly standing in Mike's room declaring herself to have done a good job.
Panel 2: As she holds up a pair of garbage bags, she tells John that with Mike away, she's been able to clean out his room without his pointless and evil objections (whose sole purpose is to destroy Elly's right to express herself and no other) about how a mere child deserves privacy and to have his property respected.
Panel 3: She then says that she can't see him missing it even if he were to find out. Since the two of them aren't going to say anything, she doesn't see how that is going to happen. What she doesn't notice is that Lizzie is listening.
Panel 4: Lynn would have us believe that the manic grin on Lizzie's face says that she's going to spread chaos by diming out her poor mother who only wanted to save Mike from the idea that he has the right to decide what he can own.
Summary: What makes this absurd is that Mike would have found out anyway because, despite what John and Elly need to believe, children aren't stupid and actually remember things. (As a matter of fact, Mike once victimized Elly by remembering other stuff of his that she helpfully freed him from.)
