Electricity follows the path of least resistance to ground.
Drop a plug on the concrete floor and bend one of those four prongs so there is very little gap.
That very small gap will be the path of least resistance to ground.
The spark will now....always jump that very small gap.
It will be a very weak spark.
Possibly causing miss fires.
There are gap specs. on plugs for a reason.
Plug gap should be checked no matter how many prongs they have.
