Panel 1: A little while after the "one hair at a time" remark, Liz unhinges her jaw so she can yell at Mike about how he isn't finished yet because she wants to GET IN THERE!!!!
Panel 2: He sets himself up for a juvenile rank-out by telling her that he isn't coming out until his hair looks meticulous.
Panel 3: When he gets out of the washroom, he says "There!"; this allows her to start in being a petty little jerk by telling them that he's right.
Panel 4: What he's supposedly right about is that he looks ridiculous.
Summary: If the notes macro works the way I think it's programmed to, Aaron will get a good scraping for being vain because he cares about what people outside the family think of him. Holly from Stone Soup is the victim of the same sort of "humor" for the same stupid damned reason.
