The original title, "Tex X", was used because it could be mistaken for an X-rated film, however "Black Bart" was rejected to avoid a reference to Black Bart, a white highwayman of the 19th century, and "Purple Sage" was also rejected. Brooks said he finally conceived "Blazing Saddles" one morning while taking a shower.

This example is DON'T KNOW.
