I love these clips, as well as the understated UK humor. In the states we are relegated quite often to old re-runs of Never the Twain, Keeping Up Appearances, Are you Being Served... I love Hyacinth though. I think she was a Grammar teacher of mine in early primary school. We also just had a crazy cross dressing guy on late night cable. Eddie Izzard, now that is a straight up crazy guy. Loved his humor context of history.

It does sound like you might be being 'force fed' at least
some of the less subtle stuff ( Never the Twain , Are you being served ) - but I am gratified to hear ( as a human being, not just as a U.K. resident ) that you enjoy the under stated aspects.
From your side of the Atlantic, my own favourite 'Wit' - and the master of grossly understating understatement - is Steven Wright. The man who so rightly once described himself as " A peripheral visionary" . Not everyone's cup of tea , but he tickles the imagination so delightfully . A true gem.

Welcome to the forum, and Peace to you too. :)
