I considered it; I've done a good bit of Wikipedia editing in the past. The problem is, I have a hard time figuring out how to phrase it better without just including the Feynman quote. That's the only source, and it seems that the Wikipedia page is merely trying to re-phrase what Feynman said; there really isn't anything to the page other than Feynman's quote and the diagrams. As such, it's hard to do a good job rephrasing it rather than simply quoting Feynman.
If you can find other sources than Feynman on the shaft passer (and blog posts and forum discussion that are merely discussing Feynman don't count), I'll consider updating it with an improved description and reference to the other sources.
