Charlie Brown Christmas Segment - Snoopy Dancing

Again, going through some old videos when I came across Charlie Brown's Christmas (a classic in my book). I decided to watch the whole thing lol...since I was a kid, my favorite part was when Schroeder was playing a song on the piano and Snoopy started dancing to it...I dunno why but I always found that part hilarious. Why did they get mad at him? Anyway, here is that part...enjoy. Also thanks to UMLinus101 for allowing me to post this video.
