In Which Pop and Ma Go on Holiday: Worried that Pop is working too hard, Ma books a weekend in Margate. Charley and Mariette are left to mind the kids and sort out the new TV aerial. Meantime, Tom Fisher is making his move and asks Mariette on a date, much to Charley's chagrin. Margate is a bit of a letdown, but Ma and Pop try to make the best of it, despite an incident with Ma's new tangerine swimsuit.
