These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Also pretty much the entirety of "Just A Small Funeral", particularly the end. Doubles as a Tear Jerker; you can tell the cast aren't acting but genuinely upset.
There are quite a few where Clegg is concerned in the later years:
In one episode, Clegg hangs a "Do Not Disturb" sign on his front door. Naturally, this causes a small crowd to gather around his house due to curiosity, including Turly, Billy, Howard and Pearl. As they're wondering what he's doing, one person suggests he's committed suicide. Truly is infuriated by the very notion and orders the man to leave for spreading "vicious rumours."
Another one comes on his birthday. Clegg just wants a quiet birthday by himself, and decides to spend it with Truly having lunch at a nice hotel. Unfortunately, there's a wedding reception at the same hotel, and everyone else is there. Naturally, in the end, everyone finds out that it's Clegg's birthday, and Pearl - at first looking like she's going to yell at him - sweetly says, "Happy Birthday, Norman." And then Truly leads everyone in a round of "Happy Birthday to you!"
There is one occasion when Clegg's cousin Aubrey comes over and is insistent that someone of Clegg's age shouldn't be wandering around without a purpose and keeps him inside all day. Truly, Alvin and Billy scheme to free him and manage to trick Aubrey into getting drunk enough that they can stick him on a bus home, much to Clegg's delight.
To add to that, the same episode reveals that Pearl often buys milk for Clegg.
Compo and Clegg's friendship in general. Any time Clegg will say something about Compo that fits his character, Compo will very enthusiastically agree with, "You're RIGHT, Norm! You're RIGHT!" It's enough to make anyone smile.
Seasonal Rot- At first, the show was almost entirely character and dialogue-based comedy with bits of light physical humor sprinkled in here and there. Also included fair amounts of smoking, drinking and swearing. Now it's generally known as a slapstick-based show and an oasis of "clean" comedy. (Although the drinking hasn't been eliminated, only downplayed. And no word on how all the humorous adultery fits into this image.)
On the subject of drinking, large pints of bitter being drunk by old men in rural pubs- especially in the north of England- doesn't really have unwholesome connotations in Britain, in fact if anything it's the opposite.
As for the adultery...since Howard and Marina apparently NEVER manage to do much of anything together, it's pretty much non-existent.
Squick- Clegg is cripplingly susceptible to it, particularly anything involving women and sex. He completely falls apart any time a woman, especially Marina, comes on to him.
