I hope you have
your towel...
Towel Day was created back in 2001 to celebrate the life of
Douglas Adams and his best know creation,
The Hitchhiker's Guide to the Galaxy
The origin of the towel joke
The full version of this story was first found in The Hitchhiker's Guide to the Galaxy: The Original Radio Scripts and reprised in The Salmon of Doubt, but the short version is as follows: Adams had gone on holiday in Greece, but every time he had decided to go to the beach with his fellows, he discovered that his towel would disappear, and could only be found after hours of searching. After the holiday had ended, he decided that anyone who really had their life in order would "know where their towel is". He had no idea that this towel joke, which first appeared in the seventh radio episode, and subsequently in the first book, would catch on so brilliantly. He assumed, after learning that so many people liked and understood the joke, that he was not the only one with such an experience. After his death, Towel Day was established on May 25 as a tribute.
Here's hoping your towel is serving you well.
