(AP) — With the clock winding down in the first half, a fan dressed as an official grabbed the ball and streaked across the field.
The man started taking off his clothes and had gotten down to his underwear when a security guard took him out with a crushing tackle.
It turned out to be as good as any tackle UCLA made in the first half.
Overmatched from Arizona's opening drive, the Bruins fell into a 35-point hole and never recovered in a 48-12 loss to the Wildcats Thursday night that will surely turn up the heat on coach Rick Neuheisel.
"It's definitely a step in the wrong direction," Neuheisel said. "I still hold out my feeling we can and will turn the corner."
It's going to be much tougher after this.
One of the nation's best rushing teams, UCLA (3-4, 2-2) had 37 yards on 25 carries against a team that was 100th in the nation at 196 yards per game. Kevin Prince was mostly ineffective in his return to the starting lineup, hitting 17 of 35 passes for 286 yards and a touchdown.
The Bruins also lost a pair of fumbles in the first half and the defense had no chance at stopping the Wildcats — ground or air — as the game quickly got out of hand.
Within a half-game of Arizona State and USC in the Pac-12 South heading into the game, the Bruins came out flat against Arizona in front of a national TV audience, putting a serious dent in their bowl chances in a game that likely won't go over well back in Southern California.
"My argument is I'm absolutely the right guy for the job," Neuheisel said. "I'm looking forward to continuing in that quest."
UCLA's biggest problem was matching Arizona's emotion.
The Wildcats were playing their first game since Mike Stoops was fired on Oct. 10 and took interim coach Tim Kish's have-fun-again approach to heart.
Dusting off an aggressive defensive scheme and relying on a recharged running game to complement Nick Foles' passing, Arizona ran over the Bruins for an emotional win.
"I had one wish for them when we left the team hotel this morning: I just wanted them to enjoy playing the game again," Kish said. "I think that wish came true."
Foles threw for 291 yards and connected with Juron Criner for three touchdown passes. That wasn't much of a surprise considering the way Arizona (2-5, 1-4 Pac-12) has piled up yards through the air.
The running game, dormant all season, came to life behind huge holes created by the much-maligned offensive line, churning out 254 of Arizona's season-high 573 yards and three touchdowns — two by Taimi Tutogi.
The defense, another sore spot under Stoops, was just as good behind a throwback scheme called the "Double Eagle Flex," an aggressive front designed to clog up lanes against good running teams.
The combination allowed the Wildcats to build a 35-point halftime lead and cruise to a big victory, ending a five-game losing streak that had cost Stoops his job last week.
"We all felt like we were out on the playground again, just little kids," Arizona linebacker Paul Vassallo said.
Frustration boiled over in the closing seconds of the first half, when a wild brawl spread about 60 yards across the field after a streaker dressed like an official ran onto the field.
Players pushed and shoved, a few wild punches were thrown and two players were ejected: Arizona defensive back Shaquille Richardson and UCLA receiver Taylor Embree.
"That was just a result of tempers flaring on both sides; it's not something we represent as a program at all, something we can't let happen," UCLA receiver Ricky Marvray said "They were just the better team tonight and they showed it."
One of Kish's main goals was to make football fun again for the Wildcats, who had lost 10 straight games against FBS opponents and eight straight in conference.
They certainly enjoyed themselves against UCLA, getting touchdowns on all six of their first-half drives while scoring 42 points, their most in a half in Pac-10/Pac-12 play and more than any of their previous six games.
Keola Antolin ran for 77 yards on just eight carries, freshman Ka'Deem Carey had an 18-yard TD run and Criner finished with 10 catches for 101 yards to give Arizona its first win over an FBS opponent since beating UCLA 29-21 last Oct. 30 in Pasadena.
"That was definitely a lot of fun," Arizona center Kyle Quinn said.
Neuheisel was concerned about Arizona's passing game and rightly so after Foles had thrown for more than 2,200 yards and 15 touchdowns the first six games.
Foles did what he expected, hitting 26 of 39 passes while connecting with Criner on TD passes of 4, 7 and 25 yards in the first half.
What Neuheisel didn't anticipate was getting run over by the Wildcats.
One of the nation's worst rushing teams, Arizona carved out huge holes in UCLA's defense that Antolin, Tutogi and Carey had no trouble racing through. The Wildcats surpassed their season average of 71.8 yards per game after one quarter and had 174 by halftime.
"We really owned the line of scrimmage on offense tonight," Kish said.
Arizona also had been plagued by slow starts, left scrambling after being outscored 41-3 in the first quarter in its previous five losses.
No such problem this time.
Foles hit Criner on a 4-yard TD pass on the Wildcats' opening drive. Carey followed with a juking, dive-for-the-pylon score from 18 yards out.
Criner added his second touchdown by snatching the ball away from UCLA's Aaron Hester early in the second quarter. UCLA fumbled, Tutogi scored on a 1-yard dive, then Foles and Criner connected again, this time from 25 yards. Another Bruins fumble, another Tutogi touchdown run, this one from 8 yards out to make it 42-7 just before halftime.
And, to think, Kish was the defensive coordinator under Stoops the past eight seasons.
"It wasn't like they did anything crazy," UCLA linebacker Patrick Larimore said. "They imposed their will on us and we weren't able to bounce back."
And, at least for the Wildcats, it sure was fun.
