Missed 2. Haven't watched it in over 30 years at least. Not really a fan of Peanuts or any of their specials. I watched as a kid because my mom made it out to be the best thing since the Halloween special (which may or may not have come after the Christmas special but was aired before for since Halloween comes first). Side note, my cousin was his attorney. I don't think I ever met my cousin.
I'm not that old. Think I may have been forced to sit through it a few times when I was young, but I have long since shredded that memory. Replaced it with something important like the main bolt torque sequence of an LQ4 I'm sure.
