If you've ever noticed items disappearing from your desk at work, you're not alone.  More than 80% of professionals who answered the "Officemax Workplace Undercover Survey" say pens, pencils and highlighters are the supplies that most frequently go missing.  Other supplies include paper products, paper clips and binder clips, staplers and scissors.

The same poll found 84% of those who admit to taking things from someone else's desk say they simply forgot to return the items - no thievery involved.  However, just over 25% say they never returned what they took because they didn't think the supplies would be missed.  And for 23%, the motivating factor was revenge.  They confess to taking items from a co-worker who had borrowed something from them and never returned it.

For some reason, I'm reminded of an episode of The Simpsons in which Homer, upon walking out to his car after work, says, "Another day, another box of stolen pens," as he throws them into the back seat of his car, already stacked high with boxes of pens he's previously taken.
