It was the day the Sooners stormed back to number one.
Crushing the Cornhuskers for 31 straight points, and a win.
That October day in 2000 was the last time OU was an underdog at home.
But can that be used as motivation this Saturday?
"I think we do well coming in as an underdog," Mark Andrews, OU sophomore tight end, said. "I think it's going to give us a chip on our shoulder. We'll be ready to go no matter what. This is a big game for us. It does give us a little bit of an edge. I think it always does, but I think we'll be ready to go either way."
The Sooners say they noticed a louder Memorial Stadium last Saturday.
But can the OU crowd best that for the Buckeyes?
"They can always be louder," Ogbonnia Okoronkwo, OU junior linebacker, said. "We're going to be out there playing Ohio State. They're a historically great program just like we are. It's going to be a big one, so I want them to be as loud as they can be."
Bob Stoops is a native of Youngstown, Ohio, so he's well aware of the Buckeyes, but Ohio State is just the latest on an impressive list of non conference opponents.
That includes schools like Alabama, Tennessee, Notre Dame and in the future LSU and Michigan.
Stoops says he and athletic director Joe Castiglione say they owe it to the Sooner fans to schedule game's like Saturday's.
"You go back through our history we've played about everybody," Stoops said. "Because we feel we owe it to our fans, and we owe it to challenge ourselves. That if you're going to be one of those top teams you need to play other like top teams, so we've done it through the years. For the most part it's been positive. Definitely."
