So in the 80's the West Indian cricket team were smashing Australia constantly. Viv Richard of course on of the stars. So in Sydney Viv was haveing a piss when an Aussie pissing next to him glance & see's Viv's large penis. He ask Viv "how you get it like that?!?"
Viv tells him to go home & tie a couple of kilo weight on the end. The man thinks that makes pefect sence & thinks after the match he'll go try it.
A week passes & another match at The Sydney Cricket Ground and the man runs into Viv again. Viv asks how's it's going for him. The man replies "well it half worked... It turned Black!"
