A group of comedians from the University of Minnesota is inching closer to a final four berth. But they need your votes. The crew is competing in Rooftop Comedy's 2012 National College Comedy Competition. The challenge -- a mix of live performance and online elimination -- started in March with 32 teams. The U of M team is facing off against Northwestern University in an online grudge match. Click here to watch their jokes and then vote. Voting end Friday at 2 p.m. central time. Team members include: Jenn Schaal, Mike Earley, Collin Klug and David Strandberg. Should they advance to the finals and win it all, the team will get the chance to perform at the Just For Laughs festival in Chicago in May.
