The temperature may be seasonably warm in New York City, but that doesn't mean Broadway.com is forgetting about the holidays: each day we're flashing back to holiday-themed videos featuring Broadway's best personalities. South Park creators Trey Parker and Matt Stone are the toast of Broadway this year thanks to their Tony-winning collaboration with Robert Lopez, The Book of Mormon. During a Comedy Central marathon of South Park Christmas episodes, the duo put on their most festive holiday sweaters to hilariously introduce each episode. During their holiday party Parker and Stone sang carols and welcomed special guests including Santa Claus and South Park favorite Mr. Hanky the Christmas Poo.
