Blackadder is a classic British comedy & period sitcom which consisted of four main series during the 1980's. It starred Rowan Atkinson as Edmund Blackadder and Tony Robinson as his dogsbody/sidekick Baldrick.
Each series was set in a different historical period covering the end of the British Middle Ages, the reign of Queen Elizabeth I, the Regency and the First World War.
There are many, many classic Blackadder moments; this cache is dedicated to one of the many cunning plans devised by Blackadder & Baldrick, in this case whilst in the trenches in Blackadder Goes Forth.
Private Baldrick: I have a plan, sir.
Captain Blackadder: Really Baldrick? A cunning and subtle one?
Private Baldrick: Yes, sir.
Captain Blackadder: As cunning as a fox who's just been appointed Professor of Cunning at Oxford University?
Private Baldrick: Yes, sir.
