The scene from Blackadder comes to mind for Richard Agars half time team talk!!
Melchett: Now, Field Marshal Haig has formulated a brilliant tactical plan to ensure final victory in the field
Blackadder: Would this brilliant plan involve us climbing over the top of our trenches and walking, very slowly towards the enemy?
Darling: How did you know that Blackadder? It's classified information
Blackadder: It's the same plan we used last time, and the seventeen times before that
Melchett: E-e-exactly! And that is what is so brilliant about it. It will catch the watchful Hun totally off guard. Doing exactly what we've done eighteen times before will be the last thing they expect us to do this time.
