My favorite is the original Grinch cartoon.
I do NOT like the Frosty cartoon. Frosty's voice gets on my nerves.
We were talking about Nestor at work the other day. It's funny how many people have never seen that one. I don't think it is/was shown on tv nearly as much as some of the others.
One I really like but haven't seen in a long time is Emmett Otters Jugband Christmas.
Janenga, the Christmas Story house is GREAT! We went a year ago and I'm sure they've added more stuff since then. Got a hilarious photo of my dad running his hand up the leg lamp. "Electric sex gleaming in the window".
