I've told a few people about this and it seemed popular, so here it is. IEEE Spectrum has an article about "The death of business-method patents", and the article's illustrations showed ridiculous patented ideas, so I googled, and they are real patents. One is about cats and the other is an astounding way of swinging.
And I found this patent application about jokes too, including self-referential ones :)
Bonus: The Yes We Scan movement is already bringing fascinating things to you, like this short video of the SR-71 :)
