As far as I know, this cartoon is still being aired despite having an ethnic stereotype. Although this cartoon will run for years to come, it will always be more famous for Howard Stern making fun of his producer's pronunciation, which he has been doing since I was in high school.
The idea here is that since Quick Draw had a Mexican sidekick, there would be other Quick Draws of other nationalities. This story, drawn by Bill Alger, was printed in Cartoon Network Presents #6 in January 1998.
