Brandon rioted after the Red Sox beat the Yankees, and he's from California. He went to the Kerry rally and didn't even vote. He went to primal scream and complained that it was gross. He doesn't even care about any of that, but he'll tell the stories over and over. He's such an experience gormandizer.
