There was an old empire that armed a cow;

I don't know how it armed a cow!

It armed the cow to get rid of the goat,

It armed the goat to get rid of the dog,

It armed the dog to get rid of the cat,

It armed the cat to get rid of the bird,

It armed the bird to get rid of the spider,

It armed the spider to get rid of the fly,

I don't know why it armed a fly, perhaps it'll die!
