I carried a towel around the campus all day. No-one noticed. I wasn’t disappointed and i’m going to observe Towel Day next year, too. You know why?
Went to the toilet? Washed your hands? You can use your towel to dry them!
Eating out? The waiter didn’t bring enough napkins? Use your towel to wipe your hands!
Too obvious? Here’s another one: Writing an SMS and the sun is bothering your screen? Use your towel to hide your phone from the sunlight!

I don’t think you can claim the Towel thing to yourself. Someone allready thought about. Douglas Adams…
I don’t think that’s too original. Someone allready thought about towels and it’s importance. Douglas Adams…Unless you didn’t try to be an original :-)
Of course it was Douglas Adams. I carried that towel, because it was the Towel Day!
