The Fatal Effects of Masturbation
This link shows a book from France in the mid 19th century and the horrible effects of Masturbation. I had so many jokes running through my head for this one, but I think you all have your own sense of humour that you can apply to this one. But God Damn, it looks like you get leprosy from wanking off.
It's safe for work, no worries, I just liked this smoking chick better than the ghastly images after the link. But if anyone can tell me where I got this picture, they're a big perv. Hah.
