Beside cleaning of our bodies we don’t accomplish anything while showering. Singing in the shower, mulling over the deep issues and things like that do not make us any smarter.
You can have fun with this Facebook shower curtain but if you want to learn while showing then have a look at this Human Skeleton Shower Curtain. Learn about insides while cleaning your outsides. This is great specially for medical students, doctors, nurses, chiropractors, and necromancers.
You can buy this for only $29.95 from Amazon.
