(Strip Number 4161, Original Publication Date, 24 April 1982)
Panel 1: It's about 7:30 on a weekday morning as Elly tells a freaked-out Michael that she thinks he's well enough to go back to school.
Panel 2: He reacts to this by yelling "No! Ma!" and making a show of coughing and wheezing.
Panel 3: He then starts channeling Doctor Smith by talking about the pain, ma, OOOOOO, the pain!!!
Panel 4: We next see him walking to the bus stop and telling Lawrence that he guesses that he overacted.
Summary: As I've said before, Elly's default assumption is that a child that looks sick and acts sick is faking so as to add to her many cruel burdens; this is not only the result of her being a paranoid idiot, it's also the result of her being a shameless liar as a child. Given that her idea of empathy is to assume that everyone in the world thinks like her, it's no wonder that a year or so down the line, Lizzie ends up in the pediatric ICU because Stupid didn't catch a disease in time. In any event, since Mike talks about his report card Monday, Lynn dodged a bullet continuity-wise because we can't honestly say that there was much Easter-themed disruption to the story.
