When I was little my grandmother told me that witches hated turtles.
So on Halloween, I came to school with my Yertle the Turtle stuffed animal and everytime I saw a witch, I whispered mysterious words to my turtle and made weird noises if the kids in witch costumes saw me...they were very confused when they turned around with me holding my turtle and saying, "heh heh heh.." under my breath.
But the controversy didn't really start until after I chased my teacher around holding out my turtle saying, "I'm gonna get you!" and shreiking with laughter.
Ok, so I made this story up. But my grandmother really did tell me that turtles scared witches.
