Though there are more than enough Halloween and Christmas cartoons, there are only a handful related to Thanksgiving that I can think of. Below is a small clip from my favorite Thanksgiving cartoon. I dare you to watch it and not have that gobble at the beginning stuck in your head.
Hee Hee. I just got this off the shelf last night (It's in volume II of the collection along with some of the Christmas episodes). I was planning on watching it with the little one this weekend. I've already taught her how to "gobble" properly.
