I had a uncle with a prosthetic leg that had black rubber toes. One day when I was small, about 7 or so, I saw this and, not knowing his leg was not a "real" leg asked him why his toes were black? He said it was from drinking coffee. I never picked up the habit of drinking coffee because I believed his story and I did not want my toes to turn black.
