Yah! 
The above statement brings back a bad memory of my 
U.S. Navy days. While stationed on an old ship, (U.S.S. 
Fulton, to be decommisioned this year) myself a electronic 
technician and an electricians mate found out the hard way that 
some stupid fool rewired our test equipment shop benches with the 
neutral and ground tied together!!!
