(Talking to peasants about the Witchsmeller Pursuivant)Edmund: Be quite Percy. Then there's something wrong with his nose and I shall know. They don't call me Clever Pit for nothing!
Baldrick: Jacke.
Edmund: What about him?
Baldrick: Clever Jacke, my-lord

The credits has the actors listed as "Cast in Order of Witchiness" and the credits alter the names of Rowan Atkinson's character to "The Great Grumbledook" and Elspet Grey's character is called "The Witch Queen".
At the very end of the episode the Queen winks to camera and wiggles her nose. This is an allusion to Samantha Stephens the witch in the show "Bewitched", which was originally broadcast for eight seasons on ABC from 1964 to 1972. It was her way of making something magical happen.
When Blackadder asks the guards if they would help him escape by dressing up as a washer woman and hiding in a wicker basket he is alluding to the escape that Toad of Toad Hall made in the book "Wind in the Willows" by Kenneth Grahame (1908).
