Every Whovian should know that the Christmas season is not complete without a good Doctor Who Christmas Special. Although there are a bunch of really great Christmas Specials, the "Doctor Who - A Christmas Carol" is by far one of NerdiPop's all-time favorite Christmas episodes. This special episode stars the beautiful and talented Katherine Jenkins as Abigail, flying fish and a flying shark (100% serious!). We love this special and watch it every Christmas Eve.
