Truth be told, I'm at best agnostic and don't care much for christmas, but I do love the Muppets, also had the pleasure of knowing Jim Henson and his 2 sons.
This is from a Christmas special.
There is also an album called John Denver and the Muppets, A Christmas Together that plays annually, like clockwork, on the evening that our tree is decorated.
At our house this dates back almost as far as the T-day playing of Alice's Restaurant.
