Rice and Tulane played last night (you mean you didn't know that?) and after the Rice mascot disagreed with a call, he decided to protest.
First, you see the mascot arguing with the official and refusing to move from the baseline. The good part comes about 1:35 into the video where you can see the Owl go a little Zidane on the official. This would be much cooler if the Texas mascot did it.
