Three Dog Night

He's a perfect stranger,
Like a cross
of himself and a fox.
He's a feeling arranger
And a changer
of the ways he talks.
He's the unforeseen danger
The keeper of
the key to the locks.
Know when you see him,
Nothing can free him.
Step aside, open wide,
It's the loner.
If you see him in the subway,
He'll be down
at the end of the car.
Watching you move
Until he knows
he knows who you are.
When you get off
