Remember that amazing emotion-inducing Pulitzer-Prize-winning WaPo article about Joshua Bell playing incognito in the Metro? Read this. The story, as in how this article came to be and what preceded it, just became even more astounding. (The same violin! It's almost like a less melodramatic version of The Red Violin, the soundtrack of which Bell performed on.)
UPDATE: Gene Weingarten also wrote a satirical column on the supposed decline of copy editors that doubles as an exercise in copy editing.
