The Ear-Shrivelling Curse (incantation unknown) causes the target's ears to shrivel up.
Prior to 1989, Bill Weasley's pen-friend from Brazil sent him a hat with this curse on it, because he was upset that Bill couldn't come to his country on an exchange trip since the Weasley family couldn't afford it. Bill's brother Charlie was present when Bill was cursed, and thought it was funny.
