Everyone has their own little superstitions, right?
Mine actually made me do something kind of good - I got out of my pajamas, despite the fact that I'm staying home today. (And tonight.)
I used to think you had to wear red, white, and blue today, or you'd get pinched or something. The consequences were murky, but dammit, you needed all three of those colors!
So today - gray shorts that say USA on one leg (cheap at Kohl's in... 04? 03?) and my Red Sox shirt from 04, for sure. It's my only blue shirt with red and white on it.
Silly, but what are you going to do?
