Toilet humour?
Here's a little product variant with a twist :: a company called Renova have created the world's first supremo black toilet paper for fancy people with fancy pants. I don't know about you but I like it...For a category like toilet tissue where innovation is usually limited to the inclusion of an additional "ply" for added softness, this is a nice departure from the norm.
