I’ve seen these guys before.
Are they for real and does anyone know the story behind them?
The two guys in the Comment you refer to might be members of two notorious families that were studied around the 1930s in the Appalacian Mts. This was a study of feeblemindedness cause by incest and inbreeding. The families were called the Jukes and the Kalikacks (sp?) if I remember correctly. Not to be confused with the Hatfields and the McCoys. My mother used to refer to them when we kids did something really stupid.
