The Galaxy Song (Monty Python, Meaning of Life)

Whenever life gets you down, Mrs. Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite eno-o-o-o-o-ough

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second, so it's reckoned
A 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, at the speed of light, you know
Twelve million miles a minute and 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 Earth
