For all of you who sat through Saturday cinema shows and TV shows with Tonto & The Lone Ranger, may I suggest a meaning to what is normally written as "Kemo Sabe."

I reckon the original meaning would have been from the Spanish, Qui Mo Sabé, "He who knows me." If that has ruined 50+ years of memories then I apologise. :-))
