Funny, but a little too obvious. What if you did a Poe's Law version of this? That is, try to create the most contrived parody of a solution to FizzBuzz possible, but one which still fools at least 50% of interviewers into thinking it's a legitimate response.
I'd love to see a branch of this with your suggestion, though... and maybe a script that would automatically generate a file structure that reflect the namespace of serious business with which one is interviewing. You know, for fun ;)
