What? You mean Aggieville is still standing? Since those riots generally happened (in my day at least) upon KSU actually *winning* a football game, they were fortunately quite rare and infrequent.

From what I hear, they don't quite classify as riots anymore--just youthful exhuberance...more like an out of control mob scene, but not really a riot. And, as you point out, it only happens when they actually win.
