The perfect toy

It thinks for itself
It goes everywhere with you
It knows every little thing
That you like to do
It can guess your future
It can recall your past
It can make itself up
It can change really fast
It knows what you’re thinking
It responds to your needs
It can get you in trouble
It can help you succeed
It requires no batteries
It goes all day long
It knows all your secrets
And your favorite songs
It’s powered by everything
It thinks learning is fun
It’s built for a lifetime
And you’ll only need one
How much does it cost?
Where can you buy it?
Is there simply a place
Where you can go try it?
Well, I’ll tell you this, child
It ain’t hard to find
It’s the thing between your ears.
And this thing is called your mind.
