(Original Publication Date, 23 January 1991)
Panel 1: Having come across a sort of birthday party with no immediately understandable occasion attached to it, Mike asks John and Elly why they're acting like it's Liz's birthday. Elly tells him that it's Elizabeth Day.
Panel 2: We can probably expect notes about fungus people when John tells Mike that they've officially declared it Elizabeth Day in honour of Liz who's nine-and-a-half years old. Instead of being a fungus person and telling John that Liz is ten and a half, he simply asks why the celebration.
Panel 3: John tells Mike that Liz has being felt left out lately so they're having a special day to let her know that she's loved, needed and an important part of the family.
Panel 4: Liz acts like he's a boyfriend she dumped and gleefully sticks her tongue out at him because there never was and never will be a Michael Day.
Summary: This does not address the real reason why Liz's grades are in the crapper. This is about the only time John does anything that isn't go goggle-eyed with confused horror when Liz is out of sorts. This is also a transition to something else: John putting an idea in Jean's head that gets him into trouble he doesn't know about, doesn't need and (for once) doesn't deserve.
