You think you don't have syphilis, but how do really know? Has anyone you trust told you you don't have it? Have you been in contact with anyone from a big city in, say, the last year? Then you almost certainly have it. Talk to your doctor immediately, or at the very least, a silver-haired white guy with an authoritative voice. He will put your shame under a microscope and make you look at it and if that doesn't change your ways, than I don't know what! Or you can just watch RiffTrax latest hilarious short subject Know For Sure.
