Very, very funny. Articles written in the style of the subject are probably the only self-referencing ones that actually work, and it works fantastically well here. Keeping the article brief was a good move, becuase it stops the joke from going stale.
A universal topic that has been well-mined for humour. The Rule might be a little obscure (and unlikely to ever have its parody searched for), but it's easily understood anyway.
Prose and formatting:
Well-written piece, as befitting an article on a language technique. No complaints!
Bit light on pictures, though that is probably best given how short the article is. Lesbian picture is extremely irrelevant, but that's Uncyclopedia. That makes it qualify for NSFW though.
Averaged your score.
Only needs work on the images, they could be better chosen in my opinion. You may wish to at least add a third to fit the rule! (not counting the Wikipedia template) If you're keeping the lesbian pic, tag the article as NSFW.
