George Constanza style, BuckMaster?
I've been accused of sleeping on the job, but have never actually done so.
One day I was troubleshooting a problem on a PC, and I kept getting stumped. I rested my head on my desk, with my hands folded in my lap, trying to go over all of the things I tried in my head in hopes that I might have overlooked something. A (l)user walked into my office and said something along the lines of "No wonder it takes forever for things to get done around here!". I just laughed (and prayed that nothing negative would come of it).
