It is 01:00. I'm at work, chasing an insidious bug inside a Java HTML parser. I'm the only one here. I've been here, alone, almost three hours. I've just realized I have no music on. The waste!
It is time to indulge in some high-volume Wagner. Ah!
p.s. wouldn't you know it -- two minutes after typing the above, I've verified that I have indeed squashed the bug (it was a badly-formed regexp causing rare failures in some substitution), and all I have left to do is package the fixed code and send it off, leaving Wagner barely past the Vorspiel... What a double waste!
