Don't take the elevator?
Just attending the OU/Texas game puts a quash on any idea that OU fans (or Texas fans) are angels. There was a time that if you were in an elevator and the door opened, you had to be prepared to answer OU or Texas to a gang of thugs staring at you. Answer wrong, and you got the crap kicked out of you. That kind of behavior has actually lessened over the years. It used to be real bad.
