Sorry it's such poor quality but my computer doesn't have enough space for me to convert it to a different format. Anyway-
Sean Penn came to San Francisco State University on December 7th to give a speech that (kind of) endorsed Dennis Kucinich. He talked about a few other things as well. Towards the end of the speech, the president of SFSU's College Republicans, Leigh Wolf, stood up in front of the podium and held a sign that said "Stop supporting America's Enemies"- possibly in reference to Penn's feelings about Hugo Chavez. A Kucinich supporter confronts Wolf and there's a minor scuffle.
After Wolf's first sign is ripped, he holds up another one that says "Hey Sean, have you seen a UFO too?" referencing Kucinich's claim he had seen one.
