I've thought about it for a good while, but really nothing beats Blackadder at it's peak and this season is the bulk of that peak (Blackadder the third has one particular episode about a dictionary which can't be ignored). The first series was pretty good but Blackadder II truly elevated this series right to the top, this is the series where the characters become fully established and the style of humour has been perfected. The cast contains British comedy royalty: Rowan Atkinson, Stephen Fry, Rik Mayall and Ade Edmondson to name a few. If you still aren't convinced I'm rating this ahead of shows like Fawlty Towers, Only Fools and Horses and Father Ted (and I'm Irish).
