Not to start a hat war, as I know that certain mainline guys are required to wear the hat. But I've noticed a correlation between tool-dom and hat wearing.

Of course, I've encountered tools who weren't wearing a hat. And I have flown with great guys who happened to have a hat. But it's my decidedly unscientific observation that when a guy shows up with a hat (God forbid, especially the ones who are wearing a hat, but just the white shirt -- no jacket or blazer), then you're more likely to be in for a lonnng trip.

And wearing your hat indoors at the LaQuinta breakfast buffet...it just defies belief, really.

And finally, there needs to be some kind of reg prohibiting regional FOs (myself included) from wearing a hat. Ever...
