Muppet Family Christmas is basically a wet dream for Muppet lovers. The Muppet Show muppets sing carols at Fozzie Bear's mom's house with everyone from Sesame Street and Fraggle Rock (plus a Muppet Babies appearance, to boot). It's one of the last few specials they did before the (first) Disney merger (and Jim Henson's unfortunate passing). An excellent overview/critique can be found at http://toughpigs.com/myweekxmasmore03.htm (in two sections).
