And now for something completely different....

The Galaxy Song

from Monty Python's THE MEANING OF LIFE

 Just…

Re-member that you’re standing on a planet that's evolving,

And revolving at nine hundred miles an hour...

That's orbiting at ninety miles a second, so it's reckoned,

The sun that is the source of all our power.

The sun and you and me, and all the stars that we can see,

Are moving at a million miles a day.

In an outer spiral-arm at forty thousand miles an hour

Of the galaxy we call the Milky Way.

Our galaxy itself contains a hundred billion stars,

It’s a hundred thousand light-years side to side.

It bulges in the middle, sixteen thousand light-years thick,

But out by us it's just three thousand light-years wide.

We're thirty thousand light-years from galactic central point,

We go 'round every two hundred million years.

And our galaxy is only one of millions of billions,

In this amazing and expanding universe.

The universe itself keeps on expanding and expanding,

In all of the directions it can whiz.

As fast as it can go, that's the speed of light you know;

Twelve million miles a minute, that's the fastest speed there is.

So remember when you’re feeling very small and insecure,

How amazingly unlikely is your birth,

And pray that there's intelligent life somewhere up in space,

'Cause there's bugger-all down here on the earth!
