A couple years ago, while going through DFW on a trip, I "happened" to be wearing a Brian Westbrook jersey (and yeah, he's an Eagle, for those who don't know).

The screener at the WTMD looked at me and said "Y'know, not only does that jersey get you a secondary, but then we send you to the Cowboys store and you gotta get a real jersey!" My reply - "Heck, we gave ya T.O., what more do ya want?" Both of us laughed about it, and no, I didn't get secondaried. Just a couple sports fans and some good-natured ribbing.

Point is, if you're gonna wear the enemy's colors (especially the Cowboys!) in PHL, be ready to take some heat!
