As someone caught out by this, most of us had speakers and windows had volume controls as well. They're kinda useless to have super low volume, so the tendency was to turn the speakers up and have windows control it. (what could go wrong? mine was always set low in windows, this was before lots of ads on browsers would randomly come on too) Fortunately everyone thought it was the guy in the cubicle next to me, with about 10-15 heads popping out of cubicles in our direction.

And for what it's worth the audio clip finished with an enthusiastic "YEE HAW"
