Yeah, or didja ever stay at a hotel that has those new magnetic-card-reader
locks?  Ever try to explain to the front desk clerk that your card won't work
anymore, because you spent the day at a monitor manufacturer and had occasion
to do some degaussing?  (You know the routine: turn on the coil, wave it 
around the tube, slowly back off, sweep the coil down near your pants pocket,
realize what you've done, yell "Aw, SHIT!!!!!.....":-))
