The Big bang theory theme (barenaked ladies):
Lyrics:
Our whole universe was in a hot dense state,
Then nearly fourteen billion years ago expansion started. Wait...
The Earth began to cool,
The autotrophs began to drool,
Neanderthals developed tools,
We built a wall, we built the pyramids,
Math, science, history, unravelling the mysteries,
That all started with the big bang! BANG!
