Do you mean Grandad or Uncle Albert's will ? because uncle Albert left them some money which they paid off the Inland Revenue with (or something like that) in one of the last episodes.
as a massive only fools fan they should've stopped when they became rich as the story was then complete. the subsequent episodes were poor imitations.
slightly ot but the other morning I was watching Citizen Smith (another John Sullivan sitcom that aired before only fools) and john challis was in it basically playing boycie!
Should have stopped it after episode 1!
I've never understood its popularity but being critical of it is like being critical of Diana, people go ballistic!
Not sure about the answer to this.
One of my favourite moments though was when they went to scatter his ashes at sea (from the back of a cross-channel ferry) and Del says something like "...and do it with some ceremony Rodney, don't just empty it out like an old hoover bag!"
