I'm not sure what they had to tell those people to get them to do so much dumb shit in front of camera (presumably) for free, but it's probably the same kind of spiel that gets girls to take their shirts off for "Girls Gone Wild" or people to interact with Sasha Baron Cohen for Ali G., Bruno or Borat. Apparently it applies to sports as well.
Step 1: Assemble a camera crew. Step 2: Travel to the parking lots of the nearest professional sports arena (preferably football). Step 3: Say you are taping for some sort of a TV show/news program/documentary and, Step 4: Ask a bunch of drunken, idiotic sports fans how much they hate the opposing team. Magic!
Come to think of it, couple this with what we learned in the last post and a small amount of venture capital, and I think we'd have enough content to keep this site running through the end of football season.
