Emmet Otters Jugband Christmas was always my favorite. I just wish Disney would release the original and uncut version the 1st aired years ago. That ranks up there with Mickeys Christmas Carol too.
Emmet is one of my favorites too. Me and the family still watch it on Christmas morning after I make breakfast.
Another special I wish Disney would release un-cut would be when the Muppets visit Fozzy's mom for Christmas. You get to see the whole Henson family of creations and then a cameo by the master himself.
