LiveScience reports: “Fishermen have long known that you can drive earthworms to the surface with a strange technique called worm grunting.

The trick involves driving a wooden stake into the ground and then rubbing the top of the stake with a long piece of steel called a rooping iron. It generates a peculiar grunting sound that drives nearby earthworms to the surface where they can be easily collected for fish bait.”

I wonder if something similar could get the worms out of congress.
