Lyrics of My understanding is zero

My understanding is zero for the simple fact, i'm not a hero
Born broke, beat up and always acting evil
I'm playin' for keeps, i gots to carry my shank
Keep my hands on my thang while i'm checkin' my bank

I gots nothin' to lose and i'd rather be six feet deep
I sing the blues 'cause i'm deep and i don't sleep
My understanding's zero watchin' channel fuzz
I don't like the fuzz, i'm like was not was

And if i was not, then i was not or will be
You better murder me man, i'm tellin' y'all to kill me
The u n h o l y, that's what they call me
My last word's is like, "fuck all y'all, g"

Before i die, i'm takin' muthafuckaz out with me
And when i die the meat wagon's gonna come and get me
My understanding's zero 'cause i'm just a zero
I hear no, i say no, i see no, no evil yo!

Is i crazy, is i am, is i am?
My butcher knife's bloody so fuck a film flam
And 'bout your god, 'bout your god
Your god is money man, in god we trust
The ill rhyme i bust, oh!

I fall into a state, i'm in depression
Playin' me a game of true confessions
I want y'all to know, i want y'all to know
If you grow up in the ghetto
Your understanding's zero
