This reminds me of a story I once read somewhere:

When Arthur returned to civilization after being raised by Merlin in seclusion, people asked what spells he was taught by the wizard.
He replied, "Spells? I don't know, but he did teach me words. When I was little he told me to eat, then he told me to sleep, and later on to walk. I've been eating, sleeping and walking ever since, so those must be potent spells indeed."
