I know of three different Christmas episodes of the Peanuts series. I don't care much for Rerun trying to get a dog one; but Rerun's always annoyed the fuck out of me. The Patty in a sheep costume one is cute (Patty as a sheep: "Woof! Meow! Moo! Whatever! And a partridge in a pear tree!"). The original is simply lovely in its innocence.
I like the Halloween one, merely because I just know that in about ten years, Sally will be dragging Linus' ass out to the pumpkin patch and it won't be about the Great Pumpkin.
Thanksgiving one could have been better (the one with Patty inviting herself and everyone else to T-day dinner at Charlie Brown's).
Easter Beagle was cute.
Didn't care too much for the New Year's and Valentine's Day ones.
On another note, I tend to have a soft spot in my heart for the Peanuts because I played Lucy in a production of "You're a Good Man, Charlie Brown". Despite it being almost 20 years ago, I'm still in contact with most all of my castmates.
