An imp is a mythological being similar to a fairy or demon. Imps are often mischievous rather than evil or harmful and they are often portrayed as lonely little creatures always in search of human attention. They often use jokes and pranks as a means of attracting human friendship, which often backfires when people become tired or annoyed. Everyone is familiar with kitchen imps. They leave jars open, crumbs on the floor, they swim in the milk and sleep in the sugar bowl.
