Lizzie is working on a float for a Christmas parade. When she finds herself competing against Kate, Lizzie gets more obsessed with winning the Christmas contest. Lizzie wants Gordo to help her, but he decides to help Mr. and Mrs. McGuire at the retirement home fixing broken pipes. That's when Lizzie discovers the true meaning of Christmas: doing something good for others.
Nobby the elf was such a jolly character for this special ep. The big surprise is that you see that Santa Claus is really Aerosmith's Steven Tyler singing "Santa Claus Is Coming to Town". I would say "best Christmas special ever" really applies to Lizzie McGuire.
