a stroke, of course - due to its double meaning the term is often used in jokes. E.g. 
'a flasher exposed himself to 2 nuns. one had a stroke, the other couldn't reach'.
If you try this with leprosy it doesn't work:
'a flasher exposed himself to 2 nuns. one caught leprosy, the other couldn't reach'.
Easy peasy gentlemen, lets up the game a little :)
 
 

 

From a purely semantic point of view, 'leprosy' is the meatier of the two (a word that the Monty Python brigade may define as sounding woody in nature) whereas 'stroke' sounds far more pleasant.  I believe it was Peter De Lane who described a stroke as being a rather nice sounding ailment; in league with being taken down by a cuddle.  As it is eternally more taxing to derive humour from pleasantness, and indeed any type of warm fuzzy comfort, it must therefore be argued that 'stroke' should not even be in the running. 
This is purely from the position of a lexophile, however.

From a physical perspective, what could be more funnier than one's conversational partner's ear falling off mid-sentence - perhaps during a dogmatic and pretentious speech about the importance of listening to one's inner self.

Food for thought, perhaps.
 

Unquestionably a banquet for the grey cells, raising, as it does, the question of whether or not physical, slapstick comedy is better than more cerebral material.  We really are kicking along now, cats and kittens.
What's interesting is that even in its early stages, the Mind Census is throwing up more questions than answers - thus proving The Moody Blues right.
At least, they were right on that score; their cameo in The Simpsons: Viva Ned Flanders was spectacularly ill-judged.
 

Alas I only have deplorable low-brow wordplay to offer. So I'll resist the temptation.
Just imagine if you will though, a leper having a stroke. Arms and legs'd be going all over the place... I'll get me coat.

 

Equivocal.
 

Salt n leper flavour crisps -leprosy? well they did taste funny to me. . . .
 

It would seem that leprosy has it all over strokes in the humour stakes, doesn't it?  Perhaps its a matter of distance: people are very unlikely to have had first-hand experience with the enlepered, but many of us have relatives - or relatives of friends - who've gone all strokey, which means it's possible to have a good old chuckle at the idea of some poor berk tottering around on necrotic stumps and counting his fingers as well as his small change every time he buys cigarettes without running the risk of someone looking all reproving and saying "I have leprosy, actually..."  It could also be argued that leprosy, being disfiguring and often terminal is shit-scary beyond belief, and the old "humour-as-defence-mechanism" kicks in; and while nobody actually looks forward to having a big old stroke, they're not perceived as being so serious, and are thus more easily contemplated without recourse to crass flippancy.  One notable exception was when Terry Woods had a stroke in Emmerdale Farm; we both thought it was fucking hilarious - so badly done, with fish-eye-lens POV shots, and all.  He recovered from it in about five episodes too, as I recall.
Now I come to think of it, this occasion gave rise to what may well be the funniest joke about illness ever - a joke so funny, in fact, as to almost make this whole day's deliberation utterly redundant: upon seeing our manic glee at Mr Woods' condition, a friend of ours (one Ms Jane Foster) said "One of these days, one of you will have a stroke - then you'll be laughing on the other side of your face!"
 

Leprosy

Easy

Tough call. I think I'm swaying towards stroke for two reasons- the first being that fucking ridiculous advert of the radio about strokes- act fast- face, arms, speech.time! While working as a pot washer I must've heard that advert hundreds of times- and for some reason the intensity of it was funny to me. The second reason being that I use the word leper too much- like if I'm tired, hung over, too fucked etc. my friends and I have somehow ended up with 'feeling like a leper' to best describe the situation. So, the potential funnyness of it has kinda been removed. Desensitised almost.

 

Leprosy is funnier, if only because there is only so far you can laugh over someone slurring, gurning  and walking in circles before you realise that you have been there yourself after heavy drinking. Laughing at stroke victims is like vigorous masturbation when you are hopelessly single; it leaves you feeling shallow and empty as though someone just held up a mirror to your soul and you pissed yourself laughing until you realised that it was you. However, no amount of inebriation however will give rise to the general flakiness and noselessness that leprosy incurs, and therefore it is a safe laugh.

 

You raise an interesting - if terrifying - point: self-knowledge, which is the aim of this week's study, can often be a burden, can't it?  Nonetheless, we're committed to the project, so let's all gird our mental loins and stick it out to the bitter end: perhaps we'll all be able to excise some of the grotesque spiritual and emotional tumours that are cramping out better nature's style once we know exactly what they are.
Or we'll just carry on living in denial and being utter cunts; time will doubtless tell - it usually does, you know.
 

 

Thank you for that report from the Moral High Ground - now back to the studio...
