The girl still running

I'm being chased by an Ox
I'm out of his sight
But I've got to keep running.
When opportunity knocks
don't put up a fight
Take it...
He's close behind but he'll never catch me
(She's the girl)
I'm the one that he was watching
(Still Running)
I'm moving fast but I'm sitting still
The more I try, the less I seem to move.
I've got to get away from the Ox
(She's the girl)
I'm the girl inside the box
(Still Running)
I'm moving fast but I'm sitting still.
I'm running in place. I'm still running
