I was born in the Congo
I walked to the Fertile Crescent and built
The Sphinx
I designed a pyramid so tough that a star
That only glows every one hundred years falls
Into the center giving divine perfect light
I am bad
I sat on the throne
Drinking nectar with Allah
I got hot and sent an ice age to Europe
To cool my thirst
My oldest daughter is Nefertiti
The tears from my birth pains
Created the Nile
I am a beautiful woman
I gazed on the forest and burned
Out the Sahara desert
With a packet of goat's meat
