It may not rank as one of the great scientific mysteries of all time, but the riddle of worm grunting has been solved, apparently.
Worm grunting, also known as worm fiddling or charming, involves driving a wooden stake into the ground and rubbing the top of it with a leaf spring or other flat piece of steel to make a grunting or snoring noise. Done in the right place under the right conditions, the result will be hundreds earthworms appearing on the surface of the ground. Worm grunting is practiced in parts of the southeast to obtain fish bait.
I am sure glad they solved the Mystery I wander how much money was spent on this?
Also I wander if they would pay me to find out the answer to my Mystery I have always wandered why my wife like me. If they pay me enough I will bug her until she tells me.
