Twenty Google engineers were charged with getting Bing to hit the honeypots and given several weeks to do so. Balancing the oddity of the query terms with the level of resources Google threw into the operation, I'm not sure if 7/100 is impressive SEO or unimpressive.
No, Wikipedia admin Nihiltres intentionally created the "torsoraphy" page (at 3:03 today, no less) and made it redirect to "Tarsorrhaphy". It's not the search algorithm being clever.
What I do know is that the original suspicious result for "torsoraphy" is returned by Wikimedia's search algorithm. http://en.wikipedia.org/wiki/Special:Search?search=torsoraph...
