Def Jam Rapstar visited by surprise musical guest

One week ago:

Joystiq's Andrew Yoon: Are you any good at rapping?

Me: What? No.

Andrew: Good, I just scheduled an appointment for you to try Def Jam Rapstar at E3.

One week later, having vigorously studied Biz Markie's "Just a Friend," I can present you with the video after the break. Big thanks must go to Def Jam Enterprises' James Waller for rapping along with me and enduring my glaring whiteness.
