Can I make fun of my father here? I'm gonna anyway.

He is permanently barred from helping the men by driving ground rods.

1st occasion, residential service upgrade. He was pushing the GR in by hand (working it up and down) when all of a sudden a slight hiss. Then water coming through the foundation. He managed to go directly through a 3/4" copper water main.

2nd occasion, service upgrade to a small strip mall. He begins to install the 1st ground rod, same as always, by hand. No hammers, drills, etc. This time an awful hiss. He went right through a 1" plastic gas main.

Now when the men see him on site with a ground rod in hand, they have orders to shoot to kill.
