Two of Disney Channel's most-watched comedies are planning a holiday-themed crossover. To kick off its month-long "Fa-la-la-lidays" programming stunt, Good Luck Charlie and Jessie will join forces in a special combined Christmas episode on Friday, Nov. 29 at 8/7c.

In "Good Luck Jessie: NYC Christmas," Good Luck Charlie's Teddy (Bridgit Mendler) and PJ (Jason Dolley) are touring colleges in New York City when a blizzard hits, preventing them from returning home to Denver for Christmas. They meet Jessie's Jessie (Debby Ryan) on the subway, and together the three celebrate the holiday in the big city.

Disney Channel also plans special holiday episodes on Sunday, Dec. 1 of Liv & Maddie (8/7c) and Austin & Ally (8:30/7:30c), and on Friday, Dec. 6, of A.N.T. Farm (8/7c), Dog with a Blog (8:30/7:30c) and Wander Over Yonder (9/8c).

The network's month-long festive lineup also includes the movies Good Luck Charlie, It's Christmas, Disney's A Christmas Carol, The Santa Clause 3: The Escape Clause and Santa Buddies.
