Blackadder: Where is the prisoner.
Baldrick: He's dead.
Blackadder: Dead? Are you sure?
Baldrick: Well I cut his head off. That usually does the trick.
In that episode of Blackadder 2, Edmund Blackadder had been put in charge of the Tower of London and had brought all the scheduled executions forward so he could enjoy a long weekend. Unfortunately Queen Elizabeth had changed her mind about killing one of her favourites. When the change of instructions got through, it was too late. With, needless to say, hilarious consequences.
