Hancock's Half Hour. There's an argument to be made that the Great British sitcom as we know it started here.
You want a misunderstood, self-proclaimed genius whose lofty ambitions in life are thwarted either by a boorish sidekick or, more often than not, his own painful shortcomings? A man trapped by circumstance? A, let's face it, pompous prig? Tony Hancock is the archetype.

Old Harry's Game. The Prince of Darkness has a lot on his plate. He was thrown out of Heaven for trying to rebel against God (or Nigel to give him his real name), although Satan claims it was more of a, "management restructuring". After the proposal, there was a lot of thunder, lightning, f-ing and blinding. Satan came to find he had horns, goat legs, and was in a place that was much, much hotter.

Dad's Army. The story begins in May 1940 with Sir Anthony Eden’s plea to men to come forward as Local Defence Volunteers. In the fictional town of Walmington, the pompous bank manager George Mainwaring declares himself commanding officer (“Times of peril always bring great men to the fore,”) and gathers together a loyal but incompetent platoon of local men to defend the town against invasion.

Revolting People. Baltimore, the 1770s - Shopkeeper Samuel Oliphant has a lot on his plate. His country is fighting for its freedom against the British, leaving him with less customers ("dead people tend to shop less"), and he has two redcoats living in his house: One-eyed, one-armed, one-legged, one nostrilled conman Sergeant McGurk, and his ineffectual officer Captain Brimshaw.

Giles Wemmbley Hogg. Comedian Marcus Brigstocke plays Hogg, an upper middle-class student ponce of Budleigh Salterton who decides to make a series of diversity-building reports while on his gap year abroad. Traveller, backpacker, fearless interviewer — Hogg has no shame in making a complete idiot of himself.

The Masterson Inheritance is "an improvised historical saga of a family at war with itself. No script, no rehearsals, just an audience and a couple of microphones". There are 3 series, each series has 6 shows. Each half hour show is improvised, with only the imagination of the performers and some sound effects to tell the story of the Masterson family.

I'm Sorry I Haven't A Clue ISIHAC has been running on BBC Radio 4 since 1972. Its success derives from the familiarity of the performers, the chemistry between them, and the warmth they inspire. And, although the show works mainly because it is clever people making fools of themselves rather than fools doing so, it is neither exclusive nor cultish. The humour is largely without any political or satirical edge. Rather old-fashioned, in fact, but it’s the funniest programme on radio.
