It's not my knee, Coach
Coach Thomas Bunch told his players during pre-season workouts that if they took a blow to a certain sensitive body area during a game, they should grab their knee instead of that body area. A Red Devil took a blow below the belt and went down on the field. Coach Bunch and others ran out to check on him, as he was grabbing his knee in pain. The Coach asked him how bad his knee was hurt, and the player managed to gasp that it wasn't his knee, and he would be ok in a couple of minutes. He returned to the game a short time later.
Lincoln County was once geographically larger. A section was returned to Wilkes County so that a resident of that area could run for Wilkes County Sheriff. This may explain that "notch" in the northwest corner of the county.
