Eminem - Rap God:
http://www.youtube.com/watch?v=XbGs_qK2PQABut I'm just a talking head, a zombie floating
But I got your mom deep throating
I'm out my ramen noodle
We have nothing in common, poodle
I'm a doberman, pinch yourself
In the arm and pay homage, pupil
It's me
My honesty's brutal
But it's honestly futile if I don't utilize
What I do though for good
At least once in a while so I wanna make sure
Somewhere in this chicken scratch I scribble and doodle
Enough rhymes to maybe try to help get some people through tough times
