So, when production is down, and clients are calling, and revenue is lost, it's okay to say "I'm too stressed to fix this bug?"

I'm sympathetic to complaints about overly technical interviews (I've bombed a few in my day because of stress and/or ignorance), but as others have pointed out, this is FizzBuzz. I'm generally very bad at interview/algorithm puzzles, but I could even figure this one out pretty quickly.
