Blackadder does contain putdowns of genius proportion:
"Percy, far from being a fit consort for a Prince of the Realm, you would bore the leggings off a village idiot. You ride a horse rather less well than another horse would, your brain would make a grain of sand look large and ungainly and the part of you that can't be mentioned, I am reliably informed by women around the court, wouldn't be worth mentioning even if it could be. If you put on a floppy hat and a furry cod-piece you might just get by as a fool, but, since you wouldn't know a joke if it got up and gave you a hair-cut, I doubt it."
"Your brain's so minute, Baldrick, that if a hungry cannibal cracked your head open, there wouldn't be enough to cover a small water biscuit."
"Personally I thought you were the least convincing female impressionist since Tarzan went through Jane's handbag and ate her lipstick, but I'm clearly in a minority."
"Everything goes over your head, doesn't it, George? You should go to Jamaica and become a limbo dancer."
"We live in an age where illness and deformity are commonplace, and yet, Ploppy, you are, without a doubt, the most repulsive individual I have ever met. I would shake your hand, but I fear it would come off."
"I know from long experience all my men have the artistic talent of a cluster of colour-blind hedgehogs in a bag."
"Bloody explorers, ponce off to Mumbo Jumbo land, come home with a tropical disease, a suntan and a bag of brown lumpy things, and Bob's your uncle, everyone's got a picture of them in their lavatory."
etc.
