This is a great cartoon for Halloween and I love it and I'm really (and I mean really) into witches.
I like it when Bugs gave Witch Hazel the "puppy-eyes"; and also, when he hands her a cup of tea to cheer Hazel up (which is really a beauty potion) and she turns a beautiful woman, and did you all know that Witch Hazel's voice actress June Foray was the model for "beautiful" Witch Hazel? I heard it on the audio commentary for this cartoon on Looney Tunes Golden Collection - Volume #2.
I also would like to point out,that there is another Witch Hazel in the 1952 Donald Duck cartoon "Trick or Treat."
