Another MTV News segment having to do with Harry Potter aired this week. While no wrockers or wizard rock bands are mentioned in the clip, Harry and the Potters t-shirts abound.

“With just five weeks before the release of the final volume, Potter-philes hole up at New York’s Horace Mann School to sleep over and share their theories.”

Check out “Slumber Party, Harry Potter Style” on MTV here. How many t-shirts can you count?
