Cutest infomercial song ever — Monty Python galaxy song

Kudos to the writers of these lyrics and melody (you can probably find the melody online but here is an updated more tame and hopefully accurate scientific version) and cute animation too.

Whenever life gets you down Mrs. Brown
and things seem hard our tough
and people are stupid obnoxious or daft
and you feel like youve had quite enough —
Just remember that you are standing
on a planet thats evolving
revolving at 1,000 miles an hour
Its orbiting at 19 miles a second
as its reckoned
a sun which is the source of all our power.
The sun and you and me
and all the stars that we can see
are moving at 12 million miles a day
In the outer spiral arm at 40,000 miles a hour
of the galaxy we call the milky way.
Our galaxy itself contains a 500 billion stars
its a 100 thousand light years side to side
it bulges in the middle 6 thousand light years thick
but out by us its just 1,000 light years wide.
We are 30,00 light years from galactic central point
we go round once every 200 million years
Our galaxy is only one of millions and billions
its an amazing and expanding universe.
The universe itself keeps on expanding and expanding
In all dimensions it can whiz
as fast as it can go, the speed of light you know
12 million miles a second and thats
the fastest speed there is.
So remember when you are feeling very small and insecure
how amazingly unlikely is your birth.
And pray that there is intelligent life
somewhere out in space
cause its bugger all down here on earth.
