Actually, my favorite demonstration of how EVERY DEVICE ON THE NETWORK MUST BE SECURE was to find a printer on the same subnet as something sensitive (Mainframes work nicely for this demo) and then change the IP address of the printer to match the IP address of the mainframe.

If there isn't a sensitive server handy, setting the printer to have the same IP address as the Default Network Gateway for its network segment is also an effective demo.
