Besides "find the porn"... this game is about as fun as you can make it given the materials you have at your will.
Materials required:
1 USA Today
1 captain or FO who is literate and social
1 pen (preferably stolen from your hotel the night before)
You flip to that page with "News from all 50 states" and you each pick a state and read (aloud works best) each little story. The one with the "worse" news gets a point. Repeat ad nauseum until you've finished all the stories.
It may not sound too fun, but some of those stories are borderline ridiculous, and it'll kill an hour and a half or so on one of those ridiculously boring legs.
Anyone got any other stupid stuff they do to kill time? Save your Ipod and book rhetoric for elsewhere.
