My desk was at a window and right outside was a ramp to the door. On the window was a white metal screen that some of the guys would scrape their hands across as they walked up the ramp to make a noise to annoy me. Being the main contact for the tech dept I was usually on the phone which made it doubly annoying. We had an old tube of white heat sink grease that leaked and was messy and should have been tossed out years before, the kind of grease that is damn near impossible to wash off your skin. I took that shit and smeared it on the white screen where they drug their hands across and it quickly put a stop to that crap.

They still did their best to annoy me but I had ways of getting even, like glue the mouse to the mousepad, switch their phone lines around so they'd get each others calls, install Teletubby windows schemes on their computers but they persisted. I finally configured workstation management stuff to shut their computers off as soon as they logged in to the server and our systems were setup to require a network login. Heheh. That one got em begging for mercy.
