''They are going to look at us as some kind of pushover,'' Sims said. ''So, we really want to shock the world next week.
''Hopefully our fans will come out and support us because this team is not going to quit.''
Brandon Weeden threw for 288 yards and five touchdowns before being pulled out of a lopsided game before halftime, and Oklahoma State went on to match its highest scoring total from the last 94 years.
It was also the second-most points allowed by Kansas, behind only a 71-10 loss to Oklahoma in 1987.
''We have some work to do on that side of the ball,'' said Kansas coach Turner Gill, whose team finishes the month with games against No. 20 Kansas State and the Longhorns. ''Or on all sides of the ball, for that matter.''
The Jayhawks offense also did plenty to feed Oklahoma State's scoring.
Jordan Webb completed 25 of 36 passes for 316 yards with two touchdowns but he also had two interceptions and lost a fumble as the Jayhawks committed four first-half turnovers - each of them leading to touchdowns on the other end.
In fact, Oklahoma State (5-0, 2-0 Big 12) scored touchdowns on all eight of its possessions before halftime against the nation's worst defense.
''I've never been a part of anything like that,'' Weeden said. ''We scored every time we touched it.''
Kansas (2-3, 0-2) came in allowing a Bowl Subdivision-worst 44.3 points per game, and Oklahoma State had already surpassed that total with 4 minutes left in the second quarter on Weeden's second TD pass to All-American receiver Justin Blackmon.
That score made it 49-7, and backup Clint Chelf tacked on a 3-yard TD pass to Hubert Anyiam with 12 seconds left before halftime to give OSU 56 consecutive points.
Chelf added 206 yards on 14 for 21 passing with two TDs. The 494 yards passing surpassed the 481 by North Carolina State - mostly by Philip Rivers - in 2003 as the most ever given up by the Jayhawks.
''It's hard to stop. They have a great tempo and it's run by a very veteran quarterback,'' Jayhawks offensive coordinator Chuck Long said. ''I think he's like six months younger than (Green Bay Packers quarterback) Aaron Rodgers.
''Being in that position, when you have a mature guy like that running things, when you call plays you know he can fix it. He's at the point of his career where he'll turn a bad play into a good one.''
There weren't many bad ones.
Weeden had the most accurate performance ever by an Oklahoma State quarterback, completing 24 of 28 passes for 85.7 percent. That was just a few percentage points better than Zac Robinson's 85.3 percent mark against Baylor two years ago.
Weeden, who turns 28 this week and is actually about two months older than Rodgers, came in as the nation's second-leading passer, trailing only Houston's Case Keenum with 398 yards per game, and will drop off in that category despite a brilliant performance. Of his incompletions, one was dropped by Blackmon on a screen pass and he purposely threw one away out the back of the end zone.
By halftime, he was already wearing a black ballcap backward on the sideline.
The Cowboys scored their most first-quarter points in the modern era with 35 and tied the school mark with 56 points in a half.
That doesn't include early blowouts, including a 117-0 shutout of Southwestern Oklahoma State in 1916 that was the last time the program scored more than 70 points in a game or a 134-0 win against Phillips that represents the school scoring record.
The only time OSU has reached 70 points since 1916 was a 70-7 win against Southern Illinois in 1973.
The Pokes came in as the nation's sixth-highest scoring team (46.8 ppg), second in passing (415.5 ypg) and third in total offense (571.8 ypg) and seemed to have a clear advantage.
The biggest thing they had to fear coming into the game was that it could be a trap, following a come-from-behind win at then-No. 8 Texas A&M and ahead of road games at No. 11 Texas and Missouri the next two weeks.
The Jayhawks started out strong, receiving the opening kickoff and then driving 80 yards to go up 7-0 on Jordan Webb's 10-yard touchdown pass to tight end Tim Biere. Toben Opurum sped around left end to sack Weeden on the Cowboys' first snap.
Oklahoma State needed less than 2 minutes to respond with seven straight Weeden passes, the last one a 12-yard TD toss to Josh Cooper. Blatnick then recovered Tony Pierson's fumble on the Jayhawks' next offensive snap, and OSU cashed it in three plays later on Weeden's 24-yard screen pass to Blackmon.
Anyiam also caught two scoring passes, Michael Harrison and Isaiah Anderson caught one apiece and Jeremy Smith rushed for a touchdown in his ninth straight game for Oklahoma State.
The Cowboys' eight drives for touchdowns in the first half averaged 84 seconds.
Coach Mike Gundy pulled his starters before halftime and didn't flinch when Kansas blocked a punt and scored just over 2 minutes into the second half.
''I like Turner Gill and, not that we have to give mercy to anybody, but there's no reason to leave (Weeden) and Blackmon and those guys in when you're ahead by (42).
''There's just no reason to do it.''
