JH and I went half on the following device...
http://www.thinkgeek.com/gadgets/electronic/8c52/ My original idea was to plant it in either KC's cube or in the office of "the one who must not be named". KC is just fun to mess around with cuz he does the same to us. "The one who must not be named" will most definitely call the cops, SWAT, and homeland security to search the office if "the one who must not be named" can't find it within the first 10 beeps, which I believe is hilarious to watch providing that there are no negative consequences, which there most definitely will be. Wait, correction: that would still be fun to watch with negative consequences, it's just not worth losing my job so soon. Hell, just thinking about it makes me lol'ed.
anyway, we're gonna plant it in KC's cube and warn others who sit around him to feign deaf or stupidity. that should drive him nuts. of course i'm not writing where I'm planting it, i know the IT guys are reading this shit right now. =P
