19. Texas Tech vs. Texas (2008)
The Longhorns are one of the most celebrated programs in college football. But when No. 1 Texas ran into N0. 7 Texas Tech in 2008, the underdog won the game. Texas was a major powerhouse at the time with nine consecutive 10-win seasons and a recent national championship. But the Red Raiders slung mud in their face.

Texas Tech came into this game with a chip on their shoulder and led for a chunk of the game. But the Longhorns came back to lead 33-32 (via ESPN). Then receiver Michael Crabtree produced a stunning moment as he scored an iconic touchdown with only a second left on the clock.
