Myself, My Tattoo.

From The Cat That Walked By Him (Her) Self of The Just So Stories Collection (Story and Drawing by Rudyard Kipling)

On the back of my neck, between the shoulder blades? Not sure. But if ever, this will be it.

Why? This is me.

Then the Man threw his two boots and his little stone axe (that makes three) at the Cat, and the Cat ran out of the Cave and the Dog chased him up a tree; and from that day to this, Best Beloved, three proper Men out of five will always throw things at a Cat whenever they meet him, and all proper Dogs will chase him up a tree. But the Cat keeps his side of the bargain too. He will kill mice and he will be kind to Babies when he is in the house, just as long as they do not pull his tail too hard. But when he has done that, and between times, and when the moon gets up and night comes, he is the Cat that walks by himself, and all places are alike to him. Then he goes out to the Wet Wild Woods or up the Wet Wild Trees or on the Wet Wild Roofs, waving his wild tail and walking by his wild lone.
