I found this part pretty crazy as well
And yes, this has happened before, during a 2004 game between Texas and Texas A&M. After returning a blocked punt for a touchdown, Texas had its point-after try blocked by the Aggies. A&M then went through the same rigmarole as Kansas State, giving the Longhorns the one-point safety.
What's really amazing: ESPN's Brad Nessler called that game in 2004 and Thursday's Fiesta Bowl. What are the odds?
