Goodbye Humanosaurus lyrics

Just take your suitcase from my wardrobe
And pack it full of guns and bombs
Then cfcs and germ-war microbes
Weve been destroying stuff too long
And theres no home for us
Just you raise your voice in chorus
Goodbye humanosaurus

Theyll teach at schools we were cold-blooded
And that we spoke and threw a turd
How we all drowned as litter flooded
We treated earth like it was dirt
And so I must implore us
Dont go near that exit door-us (doris)
Goodbye humanosaur
Be no more us

They were big with brains the size of a [burger bap]
History has got em down as a homo sap
All that now remains
Are the overgrown fast lanes
And junk food cartons
Theyd adore us if wed just sweep up the floor-us
Goodbye humanosaur
Clean the shore
No more war
