Oh, the Grand Old Duke of York, he had ten thousand men.
He marched them up (feet up) to the top of the hill, and marched them down (feet down) again.
And when they were up, they were up (up)
And when they were down, they were down (down)
And when they were only half way up (half way up), they were neither up (up) nor down (down)
* Can also be done standing
