Watching the SuperBowl (the Ravens vs. the 49ers) in the international terminal at O'Hare was the most fun I've had in an airport.  I sat in between a mechanic flying out to Afganistan, and a Brit returning home.  We cheered the good plays, sneered at the bad, and praised or ridiculed the commercials as appropriate.  In terms of the game, I've never really bonded over sports before (I don't really get them), but it didn't matter.  The Brit put it perfectly: "I don't really understand all the rules, but I heard it was a lot like rugby.  Should be good."
