For apparently being such well-informed fans, it sure is embarrassing to see the amount of people who only react when they blast "STAND UP AND SHOUT" over the loudspeakers. They don't seem to know to stand and shout on defensive 3rd downs (or, better yet, all defensive downs). But play "STAND UP AND SHOUT" in the middle of the halftime performance and they will gladly do so.
How about a friendly reminder from the PA announcer right before the defense takes the field for the first time? "The Blackshirts need your help today, Husker fans! Be sure to stand and shout when the opponent's offense takes the huddle!"
