My wife is a Wizard of Oz person. She has quiet a collection of memorabilia, so for her BLACK Miata, I surprised her with the licence plate "WITCH" and I had a license plate frame made that said, "My Other Car Is A Broom".
We all laughed about it and she took it in good, clean fun, but some neighbors (old neighborhood!) and her workmates thought she was into witchcraft and satanism :reddevil , so we let it expire the following year. BUT, she did keep the license plate frame for years! :lol
