Here's an ad from one of my martial arts comic books. If anything in this world is a responsible course of action, it would be teaching kids that like superheroes THE WORLD'S MOST DEADLY FIGHTING ART.
But let the ad speak for itself:
Yes, this is the DEADLIEST and most TERRIFYING fighting art known to man—and WITHOUT EQUAL. Its MAIMING, MUTILATING, DISFIGURING, PARALYZING and CRIPPLING techniques are known by only a few people in the world. An expert at DIM MAK could easily kill many Judo, Karate, Kung Fu, Aikido, and Gung Fu experts at one time with only finger-tip pressure using his murderous POISON HAND WEAPONS. Instructing you step by step thru each move in this manual is none other than COUNT DANTE—“THE DEADLIEST MAN WHO EVER LIVED.” (THE CROWN PRINCE OF DEATH.)
Not to mention that "The Black Dragon Fighting Society brings you the forbidden secrets of Dim Mak "The Death Touch" in this exclusive book!"
Count Juan Rafael Danté promoted himself heavily in ads in the back of comics as "The Deadliest Man Alive." Nothing like giving yourself a nickname. Best of all? If you send away for the course, you get a free membership card in the Black Dragon Society!
As a final bit of trivia, supposedly the asshole sensei villain in the first Karate Kid movie was based on Count Danté.
