many years ago a couple of ole cowboys observed an indian drunk on fire water standing out front a Saloon near the entrance. They noticed that everytime a girl went by the indian would raise his hand and say "chance" after watching this happen time and time again. They approached the indian and asked him why he was saying "chance" after all they thought indians was suposed to say "how" when greating people. The indian took one look at the cowboys and said "Me know how! Me need chance!"
