To celebrate the holiday season, MSN Shopping and Cedric the Entertainer called on everyone across the U.S. to “Shop In Your Undies.” Cedric made his proclamation in New York’s Times Square alongside two holiday “elves” as cheering shoppers looked on.

He encouraged people to avoid the mall, skip the hassles, dress in whatever they want (or don’t want), and get everything they need for their holiday shopping using the new and improved MSN Shopping. Dozens of people took his message to heart, by joining Cedric onstage in their MSN-branded boxer shorts as cameras snapped away.

After the event, dozens of young people hopped aboard an MSN-branded truck and delivered more MSN “Shop in Your Undies” boxers and MSN Shopping bags to enthusiastic people around New York.

This slideshow shows you how it all went down – and how Shopping in Your Undies became the newest holiday craze.
