In Jay Williams's tale "The Practical Princess", a dragon demands that a king should sacrifice his daughter to him so that he will leave the rest of the kingdom alone. But the princess saves herself by making a "princess dummy" out of straw, and filling it with boiling pitch and tar. The princess dresses the dummy in one of her own gowns, then goes to the dragon's cave where she offers herself as a sacrifice. The unwitting dragon swallows the straw dummy whole, and the pitch and tar explodes inside the dragon's stomach, killing him. Afterwards, the princess observes, "Dragons are not very smart."
