One Foot in the Grave (with the grumpy pensioner Victor Meldrew) looked for all the world like a highly derivative Sitcom but due to its writer was in fact on occasion entirely brilliant.
I first starting watching it while channel surfing and Victor was quivering and insensible sitting in an Emergency Room seat covered in what looked like blood on his shirt and crotch area. After a while his long suffering wife says something to the effect “such a shame all that paint fell on you when the Shed collapsed, and I was so worried that you were knocked out...But it was so nice of the Ambulance drivers to rush that mouldy carrot to the hospital packed in Ice...:”
Also the episode set entirely in Victor's stationary car in a huge traffic jam, where after 20 minutes the rear passenger door suddenly opens and in climbs Mrs Warboys their Neighbour (who no mention had been made of up to that point) who says “Oh you haven’t moved far...and I have had a lovely lunch at that pub.”
Finally, the power cut episode where Victor’s house is hot and dark due to an outage and he gets increasingly irate. Late in the episode he is sitting in his front room chair when all the lights and fans suddenly come on. He jerks to his feet and shouts “THE RELIEF!!” at which point the power goes off again and he is plunged into darkness once more….
