I'm another long time hackernews reader and banjo player. Back in the days when we used to work in data centers, I was pulling a long late night for some server maintenance with my banjo and I heard the night security guard come in on his routine patrol. I played a bit of dueling banjos (from behind a rack). He spun on his heels and got out of there. He didn't come back through again that night.
