Funny / What a Nightmare, Charlie Brown

  • Snoopy getting a lot of enjoyment out of whipping Charlie Brown, while he was pulling the sled to show Snoopy how mushing is done.
  • There's also the part where Snoopy is dancing on top of the piano in joy before accidentally getting pulled in by the music roll and spun around multiple times before hitting the floor.
