Every year as ASU and the UofA matches up on the field, devoted fans of the schools go head to head for bragging rights as well.
Fox 10's Marcy Jones did some research on the rivalry and brings us the details.
This desert duel is anything but a joke. You could say the more-than-century-old rivalry is competitive from A to Z.
"Fight, Devils Down The Field, Fight With Your Might and Don't Ever Yield."
"Bear down Arizona, bear down red and blue, bear down Arizona…Hit 'em hard let 'em know who's who!"
"For its Hail, Hail, The Gang's All Here And It's Onward to Victory!"
"Go, go Wildcats GO Arizona, bear down!"
Today Sun Devils and Wildcats came out in full force to see who would take the oldest rivalry trophy in college football.
"Forks up! Woooo!."
"Woooo, bear down baby!"
The heated duel in the desert dates back over a hundred years and doesn't appear to be cooling off anytime soon.
Both schools even got into it over Twitter, with ASU calling upon Minions, and the UofA a bringing in Beyonce!
And even though ASU prevailed this year, at the end of the day, the state of Arizona will always be -- one big house divided.
