[Ghoulish Delight]

Disney pioneered the convention of giving cartoon characters only 4 fingers. Disney characters initially had 5 fingers in the cartoons, but once Disneyland opened and the costumed characters became so popular that had to be changed. Since the characters had normal 5-fingered hands, the cast members in the costumes could just wear white gloves, leaving their hands free too...well, I shouldn't say in polite company (or on the LoT either). To protect the guests from Goofy's roaming hands, Disney went back through their entire cartoon catalog and re-animated the characters with just 4 fingers, altering the in-park costumes to match, rendering the cast members' hands useless in their oversized 4-fingered mitts.
