I got on TV because of the poncho I was wearing! (That and perhaps the insanely intense "Let's Go State" I was apparently doing at the time...)
My vague suggestion to Cyclone Alley Central regarding props- find something that's fairly durable and all-purpose that we can continue to bring to games in the future. The flashing sunglasses were neat, but didn't do anything to help us fire the crowd or players up (not to mention you only had enough for half the people there). I know we probably can't use them anymore, but the little yellow megaphones from last year, or the giant foam cowboy hats- both of those were great props. The foam bar thing from the volleyball game vs. NU, as well as the towels from the Cyclone Classic and the UNI roadtrip- those were not bad, but require more physical effort to be effective than most people are willing to put forth for an entire game.
Maybe I shouldn't be talking because I don't have a specific suggestion, but I really hope you can come up with something awesome for KU. Is there any way we can attempt to get around the new "artificial noisemaker" rule? I know balloons are out, but maybe think of something else that toes that line? If it gets banned a week later by the Big 12 HQ, fine- we'll have already accomplished our purpose with it.
I agree with the ideas of making a sign that just says "UUUUUUU!!" Also, can we come up with a good mockery of Rock Chalk? My two:
Squawk, Squawk, Jayhawk! [Screw] yoooooou!
All Talk, Jaysquawk! [Screw] yoooooou!
If we're winning or have won, you could replace "Screw you" with "Goodbye".
