Why this rock is probably not a meteorite:

The person who sent this photo said his father, a telephone company lineman, found it under a telephone line that "had been cut in two." It's not a meteorite because it's glassy on the inside.
What is it?

Maybe another fulgurite - soil fused by a lightning strike.
