All the OU fans in my building have to wear helmets so they don't hurt themselves by bumping their heads on the wall, curb, overhead pipes, etc. I lulled them into complacency by repeatedly slapping their helmets, and after they got used to me slapping their helmets, I slapped a Powercat sticker on each of their helmets. Not one of these respect OU fans have figured out that they are now Wildcat fans.
