Mine's easy; In 2001 OSU, under first year head coach Jim Tressell beat that team up north by a score of 26-20. This made OSU 6-4 in the preseason and 1-0 in the season. In a not-so-interesting aside, I almost put up a sig with the same lyrics in it as Optimus has, but I figured that it would be more fun to keep bringing up the fact that OSU won the only game that mattered.
