I figured it out once, but that was at home and this is at work.

It's really very simple to determine.  Just put a set of headphones on
and connect one terminal of a 1.5V battery to one of the three
conductors on the headphone plug (do I need to say "use a piece of
wire"?).  Touch the other terminal of the battery to one of the other
plug conductors and see if you hear anything.  Repeat the test on all
the combinations of plug conductors and you can deduce the wiring
scheme.
