I reckon my Boss's desk could give Hugh's shed a run for its money. 6 years' worth of random items* (car rego renewals, electronics datasheets, PCB prototypes!) it's a lucky dip if you stick your hand in there. His mouse has about 0.75" of lateral and longitudinal freedom, until recently the bin was overflowing with a leaning tower of empty takeaway coffee cups, and much of his "in progress" work is connected with a tangled mass of wires which somehow clings to all the papers on his desk whilst hanging mostly over the edge.
I'm not sure if it's purposely booby trapped but if I ever touch anything I spend the next 20 minutes picking it up off the floor and trying to balance it on the desk again so it looks like I wasn't interfering

(* and that's just the desk. The immediate surrounds are fortified with boxes filled with stuff from the last time they moved offices. Unlike the desk where, on request, he can place his hands on anything from the last few years within 15 seconds, the boxes are a treasure trove of un-inventoried goodies he has long forgotten about!)
