For many many years, my father had my brother and myself convinced that "Kemo-sabe" really meant "bat-shit". The story was they had used the term on the old Lone Ranger radio shows, without knowing what it really meant. By the time the series was on TV, it was too late to change it. So, for years, we believed this.
Flash forward 20+ years later. A friend from the office and I were heading downtown, and he started relating the same story from HIS father. I'm from Chiacgo, he was from Pittsburgh, and there was no way our fathers could have ever met. I was laughing so hard I almost lost control of the car....
