Puck. I’ll follow you, I’ll lead you about a round,
Through bog, through bush, through brake, through brier:
Sometime a horse I’ll be, sometime a hound,
A hog, a headless bear, sometime a fire;
And neigh, and bark, and grunt, and roar, and burn,
Like horse, hound, hog, bear, fire, at every turn.
A Midsummer Night’s Dream, William Shakespeare
