(Strip Number 646, Original Publication Date, 4 July 1984)
Panel 1: Now that practice is over, Elly asks Phil if he'd like to stay over for supper.
Panel 2: He says "I don't know. What are you having?"
Panel 3: She says that they're having good old leftovers.
Panel 4: Her face is frozen in the Bug-Eyed Glare of Existential Horror™ because Phil asks how old said leftovers actually are.
Summary: This particular strip is a relic of the era in which Elly was known to be a sub-par cook who relied overly much on indigestible casseroles and far-too-heavy stews that left her family tired, gassy and unhappy.
