In case any of you fine hoopy froods aren't aware, today (May 25th) is Towel Day, in honour of Douglas Adams. There are Towel Day events happening all over the world—really—find one near you at the Towel Day website.
To make things even more peculiar, the Guardian reports that Terry Pratchett fans wear lilac towels on May 25th in joint support of Douglas Adams, Terry Pratchett's novel Night Watch, and Alzheimer's research. INTERN, for her part, is rocking an "under the sea" themed towel to demonstrate her support of Douglas Adams, Jacques Cousteau, the Gulf oil spill, the colour blue, and endangered starfish.
