I had to change desks recently (first time in 6 years), besides the usual office supplies found these in my desk drawer:

plastic spoon and knife (no fork here)

SQL Server 2012 MSDN disk

SQL Saturday 2011 session schedule

Chinese take out menu

a packaged wet wipe from local restaraunt

an old screw that had fallen out of the ductwork when a maintenance guy was working in the ceiling

and a 7 year old 30 page ER diagram 😛

I'll never forget that SQL Saturday though, February in Cleveland (well they picked a spot way out in the middle of nowhere) and the parking lot was a sheet of ice so everyone had trouble trying to leave when the day was over.
