This is a song about "Professor green"

I got a dollar and a dream

Are your a guy that sticks to green?

Our nation have to bow, africa

I'm a rap professor ready to test ya

You an ugly nigga, cee lo green

As: i know just what you mean

I dream of makin green/

Starin at the wall, heard a scream

A disease, involves me hittin that green

I guess these major deals ain't all they seem

My chick riding shotgun, billie jean

Its never dark cause were smoking that green

And listen to the class professor/

And that i spent the night with her
