POSTSCRIPT:OK, OK, I try and make a quick gag, and I get inundated by pedants complaining about the accuracy of the diagram. I should have known better. The following diagram is hopefully more accurate, although originally rejected as I was only really interested in the comic effect, and after all that's all Venn diagram's are really used for isn't it?

(A^C)'s gotta be pretty darn small... I'd hope ;-)
Yeah, I know, technically the diagram is not really right. As pointed out by @rbhinkley on twitter, it would have been better to have not overlapped C, but just shaded it all in. However, I opted for aesthetics over accuracy.
Should have known better with you pedants.
I think it was the right choice too... it's in the spirit of all good comedy venn diagrams, and that's important!
... but you know, minor technical inaccuracies are to a skeptic what a red-rag is to a bull ;-)
Also you've written (scuse lack of Unicode conjunction/disjunction characters - don't have special character input on my phone)
(A n B) n C
when I think you mean
(A n B) u C
Bloody pedants. Happy now Pope?
Not happy!
(Using u and n for ease of typing)
u = Union = All of one and All of the other
n = Intersection = the area where the two meet.
Your diagram shades simply A n B -> the bit that is in A and B.
If you truly mean ( A n B ) u C then you must shade all of circle C as the expression means, all of C, plus the bit that's in both A and B.

I am aware the diagram does not match the formula. The formula is correct, but the diagram is deliberately wrong for the purposes of comic effect, although I don't know why I bother some times.
Whoosh.....
That was the sound of that particular comic effect flying right over the top of my head....
And you didn't mention it to the other pedants either, so please sir, may I be excused for having not noticed it? :-)

Anonymous said, "minor technical inaccuracies are to a skeptic what a red-rag is to a bull".
Shirley that should read "waving any coloured rag" because as we skeptics know, bulls are colour blind and react to the movement.
You gotta love Venn diagram jokes :-)
If 10²³@QED was anything to go by, circle C is a subset of circle B.
Bulls are not colour blind
It must be Friday. Chill dudes!
The first venn-diagramm would be symbolized with:
(A n B) u ( A n B n C )
Is it right?
It's always bad to make fun of somebody when you're making faults along the way.
I would think you need some kind of division of set C, since while C generally does not overlap with A or B, presumably at some point skeptics have participated in publicity stunts that don't involve taking shitloads of sugar pills *ahem* I mean highly efficacious medicines.
(Thereby completely missing the point.)
A and C aren't necessarily mutually exclusive.
