Eat, shoots and leaves
This is a reference to a joke.
A panda, or such an animal, was sent to the zoo. To let visitors know what food it eats, the guards wrote: "Eat shoots and leaves (of tree). Later on, they found that the panda has escaped having killed many people because it understood it as: "eat then shoots (people) then leaves (i.e. leave the place)"
As for the burned witch, I am not sure.
