Bill Wells & Aidan Moffat: The greatest story ever told 

...and plenty of people will try and tell you where we came from, but we can only ever know what we can see, so tonight, look up to the sky, there's at least a hundred billion galaxies with a hundred billion stars and every single one could be a sun just like ours.
You see, we're all just links in a chain and all life is finite, so use your time wisely, look after your teeth, and try not to hurt anyone and remember: we invented love, and that's the greatest story ever told.
