"lurks and perks"

I have been trying to find the origin of the phrases "lurks and perks" (or "perks and lurks"!!) Meaning the extra benefits of a job or position. Any ideas??

Perks are PERQuisites, the privileges that attach to a job. Lurks might be opportunities for access to information (if you hang out in the executives' washroom or lunchroom, you hear useful things), but I'm just guessing.
