(Strip Number 5155, Original Publication Date, 19 July 1989)
Panel 1: We find Phil and the kids on the roller coaster having big fun being scared out of their minds.
Panel 2: They continue to scream in fear as the roller coaster descends down one of the steeper sections of the track.
Panel 3: They continue to zip around 'pointlessly' because it makes no sense to Lynn why a person would go on one of those things instead of going slowly on a level surface insulated from the environment in a metal carapace like a sensible person.
Panel 4: As the kids look on in bafflement, Phil pays for his immaturity by being frozen in fear.
Summary: As you will recall, there are any number of strips that focus on the cruelty of the others for wanting to subject poooooor Elly to a humiliating reminder that she's hampered by a fear of high speed and falling down and being left for dead or whatever. Today's strip is meant to show us that there's a 'reason' Lynn is terrified of most things.
