I am going to try and start another series of posts dedicated to junk you should consider for your office desk.
This isn't going to be stuff that I find on
"Think Geek" - though they have some REALLY cool stuff.
Instead, this is stuff that I would want on my desk for some unknown reason or another. Something that I wouldn't mind losing or people playing with.
Or ... something that I would probably use to kill some work related time.

My first recommendation:
Giant Chicken vs. PeterReason: The battles will wage on and on and hopefully through my next meeting.
