Here it is, as threatened/promised when we were choosing what to focus on. A tally of the 152 humourous bits in Persuasion, per chapter, and per character where the humour belongs mainly to one character. Multi-pronged skewerings (e.g. of Sir Walter and Elizabeth together, Mrs Clay and Mr Elliot together, etc) are credited to the narrator.
The solid dots are laughs with the character. The "@" signs are laughs at the character. Hold your mouse pointer over them to see the piece of the text each one refers to.
I was pleasantly surprised to see Anne come out on top. My previous impression of her as a rather solemn character must have been unduly influenced by her humour drought in chapters 1-9.
Honourable mentions go to Admiral Croft, Mrs Smith, and Mr Shepherd for bringing a lot of humour in only a few appearances.
There's no accounting for taste, so I won't go into detail about why I counted certain things as humour and left out certain others. I'll just assert that they're all even funnier than this:
Q: What did Captain Wentworth say when he trod on a thistle?
A: You pierce my sole. I am half agony; have to hop.
