I suspect this is the origin of most of the "can't code fizzbuzz" stories. More accurately "can't code fizzbuzz when terrified".

When I was younger I had my best luck at interviews when I didn't give a F and felt I was just showing up for practice because I had a perfectly good job, but this new one looked mildly interesting. I'm not sure reaction to interview stress correlates positively with dedication to your new feudal overlord.
