Not to be unoriginal, but I'd have to wholeheartedly agree with the Charlie Brown Christmas special...I try to never miss it. Watched it this year once already, and I think it is on again tomorrow night too. A true classic, and I've always been a Snoopy fan, ever since I was a kid (we even have a beagle now too
). We actually always catch "the Great Pumpkin", as well as the Thanksgiving special. Rudolph is another good one, but I did miss that one this year. Also, although this isn't "technically" a special, we watch National Lampoon's Christmas Vacation each and every year
