I think Blackadder had the greatest insults.
‘Baldrick, your head is as empty as a eunuch’s underpants.’
‘If you put on a floppy hat and a funny codpiece, you might just get by as a fool, but since you wouldn’t know a joke if it got up and gave you a haircut, I doubt it.’
‘The eyes are open, the mouth moves, but Mr Brain has long since departed, hasn’t he, Perce?’
Baldrick, you wouldn’t recognise a subtle plan if it painted itself purple and danced naked on a harpsicord singing “subtle plans are here again”.’
‘Your brain for example- is so minute, Baldrick, that if a hungry cannibal cracked your head open, there wouldn’t be enough to cover a small water biscuit.’
