I hate I missed this game now. With Arizona beating up on UCLA 42-7 in the 2nd quarter, Jace Lankow snuck onto the field dressed as a referee, blowing his whistle and stopping the play. Mr Lankow then took off running and stripping off his clothes before finally being tackled by stadium police. While everyone's attention was focused on the streaker, a brawl broke out on the opposite side of the field which resulted in both benches being cleared.

 

Here's the ESPN video.

Here's a video someone (an accomplice it appears) uploaded to YouTube showing the entire streaking incident.

 

Mr Lankow was booked by the Pima County Sheriff's office, but no word on whether he spent the night in the lock up or bailed out.
