Despite it obviously piggy-backing on Wolfram Alpha when it gets confused, I still think the normal responses are pretty good. "Where have all the flowers gone" was most likely added by hand to WA, just like all of the hilarious Siri easter eggs, and is no more impressive in terms of programming. The kid's clearly good, just not as good as an entire company of professional programmers.
