That was my thought.  I had the engine stripped down to the long block, and 
applied heat, WD40, and everything else I could think of.  I couldn't get it 
to budge.  I'm not going to try to do anything about it until I have to.  

In response to those who said that the life of the plug depends on many 
things: I might add that the compression is 130-135 all around, and I 
replaced the other plugs with platinums.  The motor burns very little oil, 
like less than a quart every 2000 miles.  It leaks a couple of drops too.
