Here is a higher quality video of Jay-z at the United Nations Association 50th anniversary gala, via MTV.

AND, by way of introduction, the Secretary General of the United Nations tries his hand at rapping. Lyrics via OG Hip Hop. The video is below. (N.B. Bill Luers is the head of the United Nations Association of the United States.)

Global Classrooms are a cinch
With the help of Merrill Lynch
When you put the org in Google
Partnerships go truly gloooobal
There is hope for Earth's salvation
With the Cisneros Foundation
With Jay-Z there's double strife
Life for children and water for life
Human health will get ahead
With the valiant work of (RED)
For the poor and doing good
Stays the job of Robin Hood
UN stays on the front burner
Thanks to our champ Ted Turner
And whole revolutions stem
From the work of UNIFEM
But tonight my special shout-out
Goes to one I can't do without
We have traveled up and down
Frisco, Atlanta, Chicago town
Yes, the king of all the doers
Is my trusty friend Bill Luers
Bill, I cannot say goodbye
So take the floor and take a bow.
Ladies and Gentlemen, Ambassador Bill Luers"

And without further ado, M.C. S-G:

My advice to the Secretary General: A valiant effort, but don't quit the day job, which, you know, includes trying to save the world.
