The Fall and Rise of Reginald Perrin is the top, absolutely.
(I used to have a sort of absurd belly-shirt that I had printed with an approximation of the GROT logo. I only wore it outside a half-dozen times or so – I’m not sure that anyone got it.)
There’s something to be said for Rising Damp, too, but it’s obviously not in the same league.
Dozens of my favourites have been mentioned already, so I’ll try to keep the redundancy down by just mentioning things that haven’t come up yet.
Spitting Image – Featuring, among other great things, some of Chris Barrie’s finest work. Best Reagan impersonation ever. Kind of weird picturing that voice coming out of “Rimmer,” though.
Nobody’s mentioned BBC Radio comedies yet?
Acropolis Now is freaking brilliant.
Saturday Night Fry, particularly the earlier incarnation.
Little Britain.
A Very Bloody History of Britain.
Tales From the Mausoleum Club. (Brilliant parodies of various gothic horror tales.)
The Mighty Boosh – Kind of like what would happen if Hunter Thompson and Douglas Adams collaborated on a show about a couple of slackers who work in a zoo. Very strange.
Allen Partridge – dear God, my sides hurt and my pants are ruined.
There’s a show I’m having a hard time remembering, where the main character is a ‘nicey’ somewhat insecure woman, and the supporting characters are a senile old neighbor lady, a live-in builder that mainly just consumes all her tea, and a west-indian cab driver. Episodes revolved around mundane tasks like going to the Tesco’s to get a new sweeper, and invariably devolved into total anarchy. What was the name of this show? I want to say the author/star’s name was Susan Smith, but I know that’s not quite right. Funny as hell, though, that show.
