Hal and Netters;
Not only is pus green, but granulocytic sarcomas or chloromas are also
green on the gross so it must be the myeloperoxidase. Also, why don't we
just change the subscribe and unsubscribe to "sign on" and "sign off".  Of
course, then we'd probably get messages like "sing on" or "sign of"
:>]. Just kidding.
