(Strip Number 4832, Original Publication Date, 7 July 1987)
Panel 1: As Mike stares at her over the cereal box in order to pay her back for 'tricking' him about the ever neat thing he slept through, Lizzie tells him to cut it out.
Panel 2: He tells a likely story about reading the cereal box.
Panel 3: As he looks right over the cereal box, she yells that he's lying about what he's doing.
Panel 4: We find him at the table, Lizzie sitting by the kitchen sink and Elly not even wanting to ask what's going on.
Summary: I think I've identified the cause of the problem. The cause I see is standing around in a housecoat slopping coffee instead of supervising Frick and Frack.
