If it’s on backwards, it’s usually because I’m riding something fast enough to worry about the wind blowing it off, because I need to get in close to look at something and the bill is an obstruction (being blind sucks), because my head hurts and the bill is making it worse, or because one of my nieces put it on my head backwards (the two year old particularly likes to do that).
…or maybe just because it pisses in someone’s Post Toasties.
I'm gonna remember that one...
