What would Feynman do?
When the original "If Feynman Applied for a job at Microsoft" was posted (<a href="http://news.ycombinator.com/item?id=1866305" rel="nofollow">http://news.ycombinator.com/item?id=1866305</a>), a lot of people commented that this doesn't actually sound like something Feynman would say.  Sheldon Cooper, maybe, but Feynman would have loved the simple, elegant solution that relied on no extra tools.
