a secretary in our office had put something down on her keyboard that caused about 200 instances of Firefox to open, she tab/alt/del's the task manager, selects all the programs and clicks shut down. well. every computer on the network instantly shut down. and there are a dozen alarms going off in all the desktops.:p :p
glad im not on the network, and now they need my compouter in 10 minutes, so im going home.
