Weener Kleener Soap
I don't think that's how you spell "wiener" or "cleaner", but I'm willing to overlook the mistake on account of the fact that my penis has been bugging me for its own soap ever since it got the wrong end of a bar I used to wash up my arms and neck after a bottle of Sriracha exploded on me. So Weener Kleener it is.
Shaped like a donut for both easy and pleasurable use, the Weener Kleener ring identifies itself as One Size Fits Most. Uh, could we get a slightly more precise unit of measurement, please? Is the diameter 1", is it 4"? Because the last thing I want to do is spend $6 on a means of sanitizing and exciting my manhood, only to discover upon its arrival that I also have to spend 20 minutes whittling its interior ring to accommodate my formidable girth.
