For those who haven't seen Run This Town yet by Jay Z featuring Rihanna and Kayne West I suggest that you do..otherwise you can not appreciate this spoof by comedian Affion Crockett.
You might recognise him from Nick Cannon's Wild N Out show on MTV Base but this comedian has been around a lot longer than that - check him out on youtube he has a Making the Band spoof too - not sure if Diddy finds it as funny though! :-)
Check it out...
I couldn't stop laughing at the Chris Brown and JayZ impressions - what a comical genuis!
