The Towel

In "The Hitchhiker's Guide to the Galaxy", we are told that a towel is the most important possession a person can have. Of its many different uses, we are told that it can be brandished as a weapon. I can tell you that while it might not be lethal in a street fight, it can do the trick if you come across a roach when you are finished with your shower. A few good swats should do the trick, but then you might want to think about letting the towel go for a cycle in the washing machine.
