What are your top upsets of all time in college athletics?

Chaminade by far. This was an NAII team beating the #1 college basketball team. Huge disparity. In football these type of teams would NEVER EVER play each other. It would be like Sioux Falls University playing LSU in football. App State was a good but unknown team to upper level division opponents. Stanford was a poor team that caught a very good team on a bad day.
