I found what I was looking for, regarding the DEAD DUNKING hoax, invented out of Joseph Smiths imagination. The article is the last one on that page. Interesting also to find that the Mormons have actually Dead Dunked HITLER, and was in the process of dunking many JEWs until they put a stop to it, (but how do they really know it was stopped)
