I’ll have to keep my eye out and my cellphone camera set up for next time I see this.  Last night, we saw a guy walking down the street wearing what looked like a piece of t-shirt just put on top of his head.  This morning, I saw a more elaborate version, which involved the sleeves being used to tie in the back, plus a jaunty little rubber band to hold it on.  I can’t wait to see what alternate use these guys come up with for actual hats.
