Sorry to shatter any illusions, but the Long Dong Silver vid is a well-executed fake. The guy who produced the vid, the same guy who introduces Long Dong to his lady friend in the original vid, appeared in a UK documentary several years later explaining how he did it.
He explained that the trick was to have 2 levels of quality within the vid and it's associated publicity. Firstly, the dong itself was a latex prosthetic that was attached to the penis of the actor. During the interview he produced one of the dongs that was used during the shooting of the vid. He said that it didn't have to be particularly detailed because of the relatively low quality of videotaping and reproduction.
The second level was in the stills photography used to support the vid. Here he used the highest quality make-up techniques to ensure that the dong looked as realistic as possible.
I've got the original magazine that the photoshoot came from and I can still remember my reactions when I saw it. I've also got the original vid and a copy of 'Mandongo', where Long Dong stars as a returning Civil War soldier in a take on 'Gone with the Wind'.
I was pretty sad to hear that it was faked, and for a long while I thought it was a double-bluff , and that saying it was a fake cock was the only way to get Long Dong shown on UK television.
cheers
