Thousands showed up for the third annual “Undie Run” at Arizona State University. The event benefits four local charities that give the clothing away to the needy.

We are STILL recovering from the massive 2010 ASU Undie Run, but we wanted to share this video that our good friend, Joey Calca made of the event. This video is just a taste of the biggest, and craziest charity event hosted on ASU campus every year. If you missed this year, stay tuned (follow us on Twitter & like us on Facebook) and we’ll be announcing details for the 2011 run soon!

Note: The above video were created by a fan of the ASU Undie Run and do not necessarily share the same views as Arizona State University or the ASU Undie Run Coalition,
