I grew up near and along the banks of the Mississippi river and I remember when I was young I would fish in the creeks than lead into the river. One day as I rounded the bend of Town creek I heard an old black man talking to himself. He hadn't seen me, so I watched for a minute or 2 to see what the heck he was doing. He had the generator out of an old hand crank telephone and he would crank like crazy while saying “Here fishy, fishy. Calling Mr. fishy”He would wait a few min. then repeat. At the time I was young and didn’t know he was trying to shock up fish as I later learned that was commonly called "Phoning them up".
