Shoot, almost missed this. I looked it up earlier in the month, and somehow got it into my head it was on May 28th. Thankfully, someone else mentioned it was Towel Day, I double checked, and so it is! For better or for worse, I had been seriously considering draping a towel around my neck for the occasion, and I haven't. Maybe next year. For this year, though, no sheepish explanations that I am indeed a serious nerd.
