Last Man Not Standing

I have created a wonderful thing.

Everyone knows that it's tremendous fun to stage an impromptu race, say, to the end of the road, or to the chip shop, or to anywhere that happens to be in the direction that you and your companions are walking in. But sometimes, of course, that isn't possible. Perhaps you're stood still, or you're in a small room, or you have shoes on that would make running dangerous. In these situations, there is one phrase which can be your saviour.

"Race you horizontal!"

The rules, of course, are simple. Once the race is agreed upon, the first person to become horizontal is the winner.

You're quite welcome.
