Sherry Tina YouWannaWitch
Da notorious 21st-century fortuneteller-scammer from Floriduh who smooth-talkingly bilked countless gullible people outta huge sums by asking them if they would like to have a black-robed sorceress with a tall pointed hat assist them with difficulties in their lives, but then never delivering on said offers.
During her time in the Land of Oz, Dorothy Gale might have much preferred to deal merely with Sherry Tina YouWannaWitch instead of the Wicked Witch of the West, since this southern dame would merely have tried to trick her, not actually harm her or her little black dog.
