[ARC5] Graphite

[Robert Eleazer]

My Dad, a mechanic his whole life, used to chuckle about a co-worker he knew 
that thought graphite was a great lubricant for everything.

And then one day there was this electric stove that quit working correctly 
and the guy decided that the buttons needed lubing - with his favorite, 
graphite.

And that was the end of that stove!
