(Blackadder shows Baldrick a potato)
Blackadder: I mean, look at this. What is it?
Baldrick: I'm surprised you've forgotten, my lord.
Blackadder: I haven't forgotten; it's a rhetorical question.
Baldrick: No, it's a potato.
Queen Elizabeth: (referring to Sir Walter Raleigh) It's him. Oh, God. Do I look absolutely divine and regal, and yet and at the same time very pretty and rather accessible?
Captain Redbeard Rum: (to Blackadder) Sir, you have a woman's buttom!
Sir Walter Raleigh refers to an expedition begun in 1552. However, Raleigh was not born until 1554.
Raleigh also states that nobody has ever gone around the Cape of Good Hope. In fact, it had been done by Bartolomeu Dias in 1488.
