This is exactly why a separate ground should be used in addition to the 3 
wire line cord.  I have seen many of the grounding prongs pull out of what 
appeared to be a good plug. If you have a bad cord and care to take a look at the 
prong, you will find that in most cases, the metal contact attached to the prong 
is very narrow and can easily be broken but remain undetected.
