The Cubicaller is the perfect silly gift for anyone who works in a cubicle like I do. $15 at Restoration Hardware. 12 volume-adjustable sounds, from ray gun to kitten and doorbell. Oh yeah, I can just see my team driving each other crazy with it now.
Go big: Maybe something a little more serious like this plush throw blanket for $49 or matching down slippers for $20.
Other ideas for co-workers: Instead of sugary treats that the office is already filled with, why not a home baked quick bread such as pumpkin or banana. Not a cook, but your co-worker is?
