The Texas-Oklahoma rivalry is an easy choice, but that game has already been played.
And besides, there are so many great traditions involved in the Texas-Texas A&M rivalry.
There's the Aggie Bonfire (pictured), a hulking mass of flame symbolizing Aggie fans' burning desire to beat Texas.
And there's the Texas Hex, where UT students burn red candles to "curse" the Aggies before the game.
Just get this story that forms the origin of the Texas Hex:
Before the 1941 game, a group of [Texas] students went to a fortune teller, Mozzelle "Madame Augusta" Hipple, for advice. The Aggies were undefeated that season and the Longhorns had not defeated A&M at Kyle Field in almost 18 years, going 10-7-1 from 1923 through 1940. The fortune teller told the students to burn red candles, symbolizing challenge and opposition. University students, alumni and fans burned red candles for the entire week before the game. The Longhorns won the football game 23-0.
The Aggies can respond in kind by working that strange Longhorn-killing magic that's worked two out of the last three years. Beating Texas would not only guarantee bowl eligibility for the struggling Aggies, but would end their national title hopes and spoil the Longhorns' dream season.
This year's game is at Kyle Field. The Vince Young-led Longhorns had to get through the 12th man before embarking on their national championship run. Let's see if Colt McCoy's can do the same.
