The other hasn't happened in more than four years, since the TCU Horned Frogs came into Norman in 2005 and beat the Sooners 17-10.
When Bedlam opens Saturday between the Sooners and Oklahoma State, OU will attempt to run that 29-game home winning streak—the nation's current longest streak— to 30 and carry it into the 2010 season.
It's something sophomore wide receiver DeJuan Miller said the Sooners pride themselves on.
"Yeah, we put a pretty big emphasis on it," Miller said. "I mean, we take pride in the way we play at home. We don't really, you know, back down from anybody that comes here. So, we do put a lot of emphasis on it. It's just like somebody coming into your backyard and taking what's yours. This is our house, so we've got to protect it.
But he said it's mainly a topic the players have discussed, not something that has been addressed administratively in the locker room.
"[It's] just among the players, not the staff," Miller said. "But I think among the players, we know that this is a pretty big game. You know, we've got a streak to uphold, and Oklahoma State's a great team. And we've got to play our best. We've got to come out and play great to beat Oklahoma State this week."
That's the other side of the story.
While a 29-game home winning streak is something to take pride in, OU simply has a chance to win another game, this time against yet another talented team.
"Yeah, it's just trying to win every game you can," said OU head coach Bob Stoops. "[The streak's] not something we focus on, but sure you take pride in it. You take pride in trying to win every game.
And that's the mindset OU redshirt freshman quarterback Landry Jones is taking into the rivalry contest.
"Yeah, I mean, it's just bettering our situation right now trying to get into whatever bowl that we can, trying to end the season on a good note," Jones said.
But it's certainly a topic of discussion and will be talked about throughout the remainder of the week.
It should be interesting to see if the Sooners maintain the nation's longest home streak when they take the field against the Cowboys at 11:30 a.m. Saturday.
