For Witch Hazel (who's all gleeful cackling and flying hairpins) there's nothing more satisfying than being reassured (by the Genie in the magic mirror) that she is, indeed, the ugliest one of all.
Yep. There's no bigger compliment than that for this snaggle-toothed old hag.
And, so (on Halloween night) when an even uglier little witch comes a-knocking at her door (hollering out "Trick or Treat!") you can be darn certain that old Witch Hazel is gonna do everything within the wickedness of her power to reclaim, once again, that crown of supreme ugliness for herself.
Anyway - (IMO) - "Broom-Stick Bunny" may have been a "Bugs Bunny" cartoon, first and foremost - But, with that aside - It was, without question, Witch Hazel (and all of her hysterical histrionics) that stole the show here, over, and over again.
