Hmmmm...for thickness....Did you ever see those competitions on The World's Strongest Man where they have 2 cars on the ramps and they gotta see who can hold them the longest? Well, if you have, I would do the same thing, except attach the grips to either side of your penis. Kids...Don't try this at home!
