Only Fools and Horses (1981)

Strained Relations (Series 4, 1985) Written after Lennard Pearce, who played Grandad, died in December 1984, this episode opens with Grandad's funeral and brings in Buster Merryfield as Uncle Albert. It is the show at its most tender: Del keeps up the patter while hiding his grief, and the moment he finally admits it is one of the best things David Jason does in the whole run. Albert's arrival also changes the household for good, so watch this before any later episode.
