More importantly, knowing that you have a towel will vastly improve your standing in the eyes of others. Who do you know that can hitchhike the breath and depth of the galaxy and know exactly where his towel is and what he used it for last?
Remember, it is very important that when you buy this all important towel you make sure that *it* is the towel you want to spend your days in the universe with. You must love it as a brother, cherish it as a friend, and wash it when necessary (sure, those stains might bring back precious memories, but who can be proud of a towel that smells? Please. Wash it. We're begging you. The towel can't keep you clean and dry when it isn't.) Name it if you need to! And in your will, bestow it on the most important person in your life... if you're willing to part with it then.
