It's well nigh impossible to pick a favourite "Blackadder," although it's very true that Miranda Richardson was *born* to play QEI, which gives the 2nd series an edge. Then again, "Ink and Incapability," the epsiode about Dr Johnson's dictionary, is a serious contender...
Johnson: (places two manuscripts on the table, but picks up the top one)
Here it is, sir: the very cornerstone of English scholarship. This book,
sir, contains every word in our beloved language.
Blackadder: Every single one, sir?
J: (confidently) Every single word, sir!
B: (to Prince) Oh, well, in that case, sir, I hope you will not object if
I also offer the Doctor my most enthusiastic contrafribblarities.
B: `Contrafribblarites', sir? It is a common word down our way.
J: Damn! (writes in the book)
B: Oh, I'm sorry, sir. I'm anus-peptic, phrasmotic, even compunctious to have
caused you such pericombobulation.
J: What? What? WHAT?
